Chapter 110 Terahertz

Zhu Cheng announced about ionic salt!Scandal about DDT!
And it’s self-media promotion!Whether it is the battle shield or the wisdom eye, these contents appear on the computer, and the detailed data tell everyone!What is capital operation.What is public opinion guidance!What is exploitation!
Since the capitalists controlled the public opinion and the media, the capitalists have never been in a panic again. They have done all kinds of bad things and turned their backs on others!But no one dared to mention these.Today, this weapon finally suddenly failed!How can the capitalists not be frightened!

The core of the anti-cancer detection and treatment device, the "miracle bullet", was also announced by Zhu Cheng.

This drug, which was suppressed by the FDA, is finally known by everyone. In fact, there is already a drug that can relieve the pain of cancer patients. Although it cannot be cured, at least it has new possibilities for symptom relief and the spread of cancerous cells. .

Zhu Cheng lifted the cover and waited quietly for the change. Can this information kill capitalists with one stick?Totally impossible.

Moreover, the data leakage has been known to the capitalists, and both Soros and Kerim are insiders.They have long been prepared.

No matter how dirty they are internally, or what kind of transactions they have.But the muzzles are unanimous!Because their interests are the same!
There have been demonstrations on the streets of various countries, demanding an explanation.From the Internet to the people, there is a lot of dissatisfaction with the shady scene and the desire to hide the truth. They shouted, hoping to get a positive answer.

Fooling the people and lowering people's wisdom is something that capitalists have always enjoyed. Countless people don't know the power of DDT and the significance of DDT to the third world!It is not clear how huge the chain of interests is behind this.Therefore, the truth that the people crave is told by the instigators—the capitalists.How ridiculous.

The "miracle bullet" finally came out of the dusty FDA archives and went to the world.

The capitalists have long been aware of the information leaked from the Google x underground laboratory, and they have long been psychologically prepared. They have long had various scapegoats.The answer given by the capitalists to the public is that a certain FDA official was corrupt.The officer was fined and imprisoned for life.

Naturally, this kind of result cannot satisfy everyone. They shouted loudly and continued to delve into this issue!They demanded the truth and criticism, but the voices of these discussions did not make the capitalists feel like they were sitting on pins and needles. This matter has been going on for a long time, and it can no longer be traced.

Within a few days, the whole world gradually quieted down. Many things will have results without fighting.Just like Martin Luther King's cry, it can only wake up a few people.

At this time, the domestic situation is calm. Whether it is the addition of calcium and magnesium ions to sea salt, or the DDT tragedy, or the anti-cancer drug hidden by the FDA, it is just a matter of conversation after dinner. They are more concerned about when Cree’s medical warehouses will be popularized in their cities. .

In the back garden of the Gemini, one machine life is roaring, Venus is regulating, and one medical warehouse is producing continuously, and then packing them into boxes for delivery to all parts of the country.

Zhu Cheng was resting in the lounge. Whether it was production, packaging, or loading and unloading, it was done by Venus Ron and the self-driving car. All of this was in order, so naturally he didn't need to worry too much.

He has already started preparing for the upgrade of the black technology library, and he needs to recharge his batteries.

Now in Carey's library, there are only a hundred first-class books, and Zhu Cheng remembers all of these books.He is just reviewing these knowledge points to prevent forgetting them during the exam.A good state can make the test results more ideal.He strives for perfection in the examination.

As a top student, he naturally knows how to adjust to improve his spirit. It is useless to study frantically before the exam.A good mental state can make him perform better.

After taking a leisurely nap, he woke up and found a message from Qixingxing.

"Sir, in the private laboratory on the top floor of the Gemini Building, the nonlinear optical crystals grown by hydrothermal method have been grown. Your plan can be implemented."

He was pleasantly surprised. This nonlinear optical crystal is the cornerstone of many technologies. It can be said that without this technology, it is impossible to open a series of technology trees. Just like Shannon's information theory status, he is called "the father of information science." In his 32-year-old master's thesis, Shannon proposed that all information in the world can be represented by 0 and 1.

And nonlinear optical crystals are lasers. The basis of this thing, like KBBF, can shorten the wavelength of lasers to achieve its purpose.

"I'll go take a look."

When Zhu Cheng got up, the living room was not extravagant. There was a desk by the window, and some papers were placed on it. It was a set of data he checked and calculated yesterday. He was summarizing all the feedback data of human body enhancement on the changes in the specificity of human body enhancement. .

There are countless greenery outside the window. After more than a month, some creatures have nested in the back garden of Gemini, and there are unknown birds outside the window.Among the treetops, a few squirrels are storing food for the winter.Chasing and playing among the treetops, holding food and playing.

It's late autumn, and the leaves are all over the ground.Several domestic robots sweep fallen leaves along the forest path.The sound of Salsa sweeping the floor and the crisp sound of birdsong echoed in Zhu Cheng's ears.

The weather seems to be much better these days, but there is one autumn rain and one cold.Qiuhu's residual prestige has gradually disappeared.Miss Dong is coming soon.

Zhu Cheng put on the jetpack and flew towards the top of the Gemini Tower. In his eyes of science and engineering, the shortest straight line between two points is a deep-rooted obsession.So he had no time to observe how eye-catching the autumn scenery was.

Nonlinear optical crystals are top-level projects in domestic scientific research, and many methods are used.But in the atmosphere, nonlinear optical crystals have only one purpose, which is terahertz waves.

Terahertz waves are known as the treasures that human beings have forgotten.Between microwave and infrared.Before it was officially named, it was called far-infrared rays, classifying her as infrared rays, and forgetting is a loss for mankind.

Terahertz is also known as one of the top ten technologies that will change the world in the 21st century.

The unique performance of terahertz has brought earth-shaking changes to the fields of communication, radar, electronic countermeasures, electromagnetic weapons, astronomy, medical imaging, non-destructive testing, security inspection and so on.

Its technical difficulty is that the source is unstable and there is no highly sensitive detector.

In fact, the principle of terahertz is not complicated. When a high-intensity, short-wavelength laser is shot on a metal polyethylene target, a stable terahertz wave and high-energy electron flow will be generated.

And this high-intensity, short-wavelength laser is the difficulty among the difficulties.Similar to KBBF nonlinear optical crystals, it is a cutting-edge product of high-tech sought after by various countries.

However, every breakthrough in nonlinear crystal technology is like buying a lottery ticket. If you touch it, it is a breakthrough. If you don’t touch it, you can only waste an experiment!
While low-energy terahertz radiation sources have been popularized in some radars and laboratories, the lack of high-energy terahertz radiation sources is an important bottleneck restricting the scientific development of terahertz technology.

At present, the international research on terahertz radiation based on laser-plasma interaction mainly focuses on the two-color laser-pumped air filament scheme. Due to the defocusing effect of the plasma on the laser, the light intensity in the filament is clamped at 10 to 15- 16 times W/cm2 or less.

Laser sources are on the one hand, and optics damage is a huge problem on the other.

Plasma can withstand the pumping of any light intensity, which can overcome the serious damage of optical components in traditional terahertz generation methods such as optical rectification.

His terahertz device awaits the arrival of nonlinear crystals.As for the first target of the terahertz attack, Zhu Cheng looked at the network communication that restricts the development of the network.

How fast is the internet?Now the vast majority of people are still using 10M, 100M, and Gigabit speeds to surf the Internet.And this network speed limits the speed of communication.

When THz technology is used for communication, a wireless transmission speed of 10GB/s can be obtained!Of course, in the atmosphere, the refraction, reflection, diffraction, and interference of terahertz will reduce this number, but it can also greatly increase the speed of Internet users!
Terahertz communications, especially satellite communications, do not need to consider the influence of the atmosphere because they are in outer space, in a state of near vacuum.This allows THz communication to carry out high-secret satellite communication with extremely high bandwidth.Zhu Cheng is solving the problem of easy wear and tear of radiation sources and equipment components!
It is no exaggeration to say that with terahertz earth communication, the era of big data will be real!A movie is downloaded in a few seconds, and the clarity of the video can be greatly improved!When the speed of communication is accelerating and the amount of information is increasing rapidly, various communication-related technologies will make great progress!
Zhu Cheng took the nonlinear optical single chip out of the aqueous solution, and then observed the color carefully under the tunnel microscope.Quite perfect!
His office is on the top floor, and his private laboratory is connected to an antenna on top of the Gemini Tower.Terahertz devices have been sitting there for a long time, waiting for nonlinear crystals to grow.

Put the crystal into the terahertz device, turn on the power, and Weng Ming started softly.A burst of invisible fluctuations touched the whole city.

"Open local area unlimited communication."

He lightly gave an order to Venus, and the wisdom eyes of Quanshan City paused for a second and returned to normal, and the communication chips inside them activated.The people in Shancheng didn't know what happened, they just got stuck, and the person who was using the smart eye to make a call suddenly found that the AR augmented reality image was very clear!Clear to the point of real ones.

At the beginning, Kerui took the position of the Big Three in communication, and the Big Three were patient.But Zhu Cheng suspects that they have a lot to do with the hijacking incident!And Zhu Cheng planned to eliminate the Big Three of communications quietly, and he was not going to tell them.

What is the concept of having WIFI anytime and anywhere in a mountain city, and the speed of the network is as high as 7G/s?Although it is only a local area network in a mountain city.
