Rebirth 2009: Synthetic God

Mou Zhongyi tiredly threw down the manuscript paper. It was a thesis written by the doctoral student below. newᴄᴏᴍ

What the hell, I still want to graduate based on my defense!

Scientific research is a very real industry. Even if many people get a Ph.D., they may not have any real talents, let alone make any meaningful progress. It is the norm for most people to write a thesis just for graduation.

The towers of science are all built on the sea, and the bottom is filled with water.

As an old professor in the field of materials, Mou Zhongyi's energy has gradually declined over the years, and his focus has gradually shifted to teaching. The older generation of scientific researchers still have relatively traditional ideas and hope to cultivate several talents for the country.

At present, this part of the focus can be regarded as feeding the dog.

After so many years of teaching, I have only produced five good ones, and all of them have gone abroad.

My wife brought a plate of fruit and said, "Why are you looking at these things when we are on vacation?"

Mou Zhongyi smiled helplessly: "Idleness is also idleness."

My wife rolled her eyes and said, "Why don't I quit next year and help take care of my granddaughter?"

Mou Zhongyi thought to himself that it would kill me.

The senior phone on the table rang. Mou Zhongyi picked it up and took a look: "Xiao Wu, Happy New Year."

"Mr. Mou, Happy New Year. Do you have time now? Are you in Shanghai?"

Mou Zhongyi smiled and said: "Are you looking for me to eat? No need, just three days of vacation to spend more time with my family. New"

"Mr. Mou, it's not about eating. I have a student here who has produced a result. I'm a little unsure. You know that I later switched to metalloenzyme. You may want to take a look."

Mou Zhongyi did not refuse: "Okay, send your paper over and let me take a look."

Wu Huamin's tone became strange: "What the student without thesis just published last night seems to be an accidental product, and now I only have one physical object in my hands."

Mou Zhongyi was stunned for a long time.

"Now it is suspected that it is a 'metamaterial' structure, an electronically controlled wave-absorbing film. I measured it with the college's instruments. Several fixed wavelengths, the reflection loss is -1dB. Equipment limitations cannot completely exclude environmental electromagnetic waves. I would like to invite a teacher. have a look."

Wu Huamin was once a graduate student of Mou Zhongyi, but when he went abroad for his PhD, his research direction took a U-turn.

The field that Mou Zhongyi specializes in is absorbing materials. Wu Huamin was able to work in the "Metal Sputtering Laboratory" later because of his experience in related fields.

Mou Zhongyi touched his chin. Although it sounded like it was probably a mistake, he was still a little interested.

It was almost dark outside the window, but Mou Zhongyi decided to go take a look and got up and put on his coat.

His wife knew what he was going to do with just a glance from the corner of his eye, and complained: "The first day of vacation! Where are you going again!"

Mou Zhongyi accompanied him with a smile: "Just go and have a look, and then come back."

His home is right next to Fuda, a 20-minute walk away. new

When he came to the second floor of the materials, he saw a young man downstairs who seemed to be waiting for him.

"Where is your teacher Wu?"

"Professor Mou, are you right? I'll take you upstairs."

It was also the first time for Zhou Rui to meet Wu Huamin's teacher.

There is a feeling of shaking people upwards.

Mou Zhongyi asked in a joking tone on the way: "Are you the student who created the 'metamaterial'? How did you do it?"

This student looked very energetic, and Mou Zhongyi unconsciously felt more favorable towards him.

Zhou Rui nodded and said: "A four-material composite coating. In a certain yet unconfirmed magnetic field environment, the deposited layer forms a new composite microphysical structure."

Mou Zhongyi thought to himself that the student said that there was a nose with eyes, and I almost believed it. He asked, "Tell me, is this material of yours a resistive loss or a dielectric loss?"

Zhou Rui thought for a while and said, "It should be biased towards magnetic loss."

Mou Zhongyi raised his eyes: "Looking at your age, you should be a graduate student. Your foundation is quite solid."

Zhou Rui pointed at himself: "Professor Mou, I look so young? Is it possible that I am an undergraduate?"

However, Zhou Rui didn’t dare to admit that he had a solid foundation. He thought that it was because I wasn’t solid enough that I didn’t grasp all the revelations from heaven.

Mou Zhongyi was stunned. As an undergraduate, he thought that his trip was most likely in vain. Forget it, just think of it as a walk.

Entering the laboratory, Wu Huamin was repeatedly turning the switch on the laboratory power supply, fascinated by the film's changing color from iron gray to mirror, with his back like a DJ playing discs.

Hearing the noise, he turned around and said immediately: "Teacher, you are here."

After showing Mou Zhongyi the magical electronic control effect.

Mou Zhongyi's relaxed expression disappeared instantly: "Tell me what's going on?"

Just as Wu Huamin was about to speak, he was interrupted by Mou Zhongyi: "Shut up, Xiao Zhou."

Zhou Rui briefly talked about what happened last night. Of course, he didn't mention the revelation from heaven. He just described it as an inspiration and luck.

Wu Huamin said excitedly: "Teacher, this may be a brand new metamaterial structure. The most important thing is that Xiao Zhou has made a finished product!"

It may take ten or even decades for a new material to go from "discovering" to "researching and understanding" to "making a finished product", but now it seems to be the other way around. You get the finished product first, and then you start guessing. what happened.

Apart from being the chosen one, Wu Huamin could not think of any other explanation.

"Do you think this could possibly be used for invisible coating?"

Mou Zhongyi frowned and thought for a long time, then looked at Zhou Rui who looked calm, but finally shook his head.

"It's too early to say that now."

Stealth coating is a general term. It is not only in the form of coatings, nor is it only used on fighter jets. In the fields of precision industry and communications, there are many scenarios where electromagnetic wave interference needs to be reduced as much as possible.

Generally speaking, it is not difficult to find a material with extremely high wave absorption rate. For example, there are many materials in nature, and graphite is one of them. If graphite is pressed into a plate, the wave absorption rate will be ridiculously high.

But you can't build a fighter jet out of graphite sheets, right?

If you want to call it an invisible coating, especially for fighter jets, wave absorption is only the basic threshold. You also need to consider high temperature resistance, ultra-high-speed flight abrasion, density, and good integration with the main structure without affecting aerodynamics. layout.

The film cannot be attached to the inside of the engine, and the appearance design also plays a very important role in the "stealth capability". Only in combination with the "stealth coating" can it be considered realistic.

Fighter aircraft are the crown jewel of the military industry, and any application is an extremely complex systematic project that requires both “needs and needs.”

But even if it's not an invisible coating, a brand new metamaterial structure and a highly malleable finished membrane are all huge things.

Mou Zhongyi took off his coat, looked a little more serious, and said to Zhou Rui: "Xiao Zhou, don't be excited, don't be excited, give me some guidance, Wu Huamin, take notes, and we will do a complete set of tests."

Zhou Ruixin said I'm not excited, but I think you shouldn't be too excited.

Wu Huamin was about to go back and get his computer. Fortunately, he had the habit of carrying it with him.

Mou Zhongyi stopped him and said in a deep voice: "Don't use the computer, write by hand."

Wu Huamin: Huh?

Then I understood the teacher's intention.

Is this film really so powerful?
