Abstract

The invention discloses a self-adapting super-surface electromagnetic invisibility cloak system and working method thereof. The system comprises a resonance module, a detecting module, a deep learningmodule and a voltage controlling module, wherein the resonance module is used for seamlessly splicing into a stealth suit; the voltage chip module is used for providing a direct current bias voltagefor the resonance module; the detecting module is used for detecting incident wave information of an electromagnetic wave and environmental background information of an invisibility cloak; and the deep learning module is used for receiving information detected by the detecting module, calculating the bias voltage value required by a resonance unit, and controlling the voltage chip module to provide a corresponding direct current bias voltage. By means of the self-adapting super-surface electromagnetic stealth system, the internal parameters is actively adjusted according to different incidentwave information and environmental background information, so that the real-time stealth is achieved; the human interference and a large number of time-consuming and laborious full-wave numerical simulation are unnecessary; and the efficiency and the sensitive reaction speed are high. The self-adapting super-surface electromagnetic invisibility cloak can be widely applied to the microwave frequency band and in the scenes with high requirements for real-time performance.

Description

technical field

[0001] The invention belongs to the field of electromagnetic wave cloaking, and in particular relates to an adaptive metasurface electromagnetic cloaking system and a working method thereof. Background technique

[0002] In biological evolution, stealth is an advanced way of self-protection. For example, cephalopods such as chameleons and octopuses change the color of their bodies to make them consistent with the background color of their habitats; the wings of penetrating butterflies can greatly reduce the reflection of light, making it difficult for predators to find. More importantly, these animals and insects can actively adjust the internal microstructure of the body according to different external environments to achieve the purpose of "stealth" in real time.

[0003] Humans have also longed for invisibility. From the famous Chinese novel Journey to the West to the current Harry Potter, people's fantasy of invisibility has never stopped. The traditio...
