Chapter 215 Determining the Potential, the Possibility of Aircraft Film

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

What a joke, you want to graduate by relying on the defense!

Scientific research is a very realistic industry. Many people, even if they have a doctorate, may not have any real skills, let alone make any meaningful progress. It is normal for most people to write a paper for graduation.

The tower of science is built on the sea, and there is water underneath.

As an old professor in the field of materials, Mou Zhongyi's energy has been gradually declining in recent years, and his focus has gradually shifted to teaching. The concepts of the older generation of scientific researchers are still relatively traditional, and they hope to cultivate a few talents for the country.

At present, this part of the focus is wasted.

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

His wife brought a plate of fruit and said, "It's vacation time, why are you still looking at these things?"

Mou Zhongyi smiled helplessly: "I'm idle anyway."

His wife rolled her eyes: "Why don't I retire next year and help take care of my granddaughter."

Mou Zhongyi thought that would be a waste of my life.

The old cell phone on the table rang, and 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: "Looking for me for dinner? No need, it's just three days of vacation, spend more time with your family."

"Mr. Mou, it's not dinner, I have a student here, who has a result, I'm a little unsure, you know I later switched to the direction of metal enzymes, maybe you need to take a look."

Mou Zhongyi didn't refuse: "Okay, send your paper to me and let me take a look."

Wu Huamin's tone became strange: "The student who didn't have a paper just published something last night, it seems to be an unexpected product, and now I only have a physical object in my hand."

Mou Zhongyi was stunned for a long time.

"Now I suspect it is a 'meta-material' structure, an electrically controlled absorbing film. I used the college's instruments to measure it. The reflection loss of several fixed wavelengths is -1dB. The equipment is limited and the environmental electromagnetic waves cannot be completely eliminated. I would like to ask the teacher to take a look."

Wu Huamin was once Mou Zhongyi's graduate student, but he went abroad during his doctoral studies and his research direction took a 180-degree 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 resume in related fields.

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

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

His wife knew what he was going to do with a glance and complained: "It's the first day of vacation! Where are you going again!"

Mou Zhongyi smiled and said: "Just go and take a look, and come back."

His home is next to Fudan University, and it takes 20 minutes to walk there.

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, right? I'll take you upstairs."

This was also the first time Zhou Rui had met Wu Huamin's teacher.

It felt like he was shaking people upstairs.

On the way, Mou Zhongyi asked jokingly, "Are you the student who came up with 'super materials'? How did you do it?"

This student looked very energetic, and Mou Zhongyi unconsciously had a better impression of him.

Zhou Rui nodded and said, "A four-material composite coating, under a certain magnetic field environment that has not yet been confirmed, the deposited layer forms a new composite microscopic physical structure."

Mou Zhongyi thought that this student's words were very convincing, and I almost believed it, so he asked, "Then tell me, is your material resistive loss or dielectric loss?"

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

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

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

But Zhou Rui didn't dare to admit it because his foundation was solid. He thought that it was because I didn't have a solid foundation that I didn't grasp all the revelations of heaven.

Mou Zhongyi was stunned. He thought that he was probably going to waste his trip as an undergraduate student. Forget it, just take it as a walk.

Entering the laboratory, Wu Huamin was repeatedly turning the switch on the power supply of the laboratory, watching the film change from iron gray to mirror color and was fascinated. His back looked like a DJ playing the disc.

He turned his head and said immediately: "Teacher, you are finally here."

After showing Mou Zhongyi the magical electric control effect.

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

Wu Huamin was about to speak when he was interrupted by Mou Zhongyi: "Shut up, Xiao Zhou, you tell me."

Zhou Rui roughly recounted what happened last night, of course he did not mention the revelation from heaven, but just described it as an inspiration plus a stroke of luck.

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

A new material may take ten or even several decades from "discovery" to "research and understanding", and then to "making a finished product", but now it seems to be the other way around, first get the finished product, and then start to guess what's going on.

Wu Huamin can't think of any other explanation except the chosen one.

"Do you think this can be used for invisible coatings?"

Mou Zhongyi frowned and thought for a while, then looked at Zhou Rui with a calm face, but finally shook his head.

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

Stealth coating is a general term. It is not only in the form of coatings, nor is it only used in fighter jets. There are many scenarios in the fields of precision industry and communications that need to minimize electromagnetic interference.

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

But you can't use graphite plates to build fighter jets, right?

If you want to call it a stealth coating, especially for fighter jets, wave absorption is only the basic threshold. You also need to consider high temperature resistance, ultra-high-speed flight wear, density, and good integration with the main structure, and do not affect the aerodynamic layout.

The film cannot be pasted inside the engine, and the appearance design also occupies a very important proportion in the "stealth capability". Finally, the combined effect with the "stealth coating" can be considered practical.

Fighter jets are the crown of the military industry. Any application is an extremely complex systematic project, which emphasizes "both and more".

But even if it is not an invisible coating, a new metamaterial structure and a highly plastic finished film are all great things.

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

Zhou Rui thought to himself that I am not excited, but I think you should not get too excited.

Wu Huamin was about to turn around to 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: ah?

Then he understood the teacher's intention.

Is this film really that amazing?
