Abstract

The invention relates to an electromagnetic energy sensing intelligent stealth metasurface. According to the stealth metasurface, an energy sensing module is used for detecting electromagnetic characteristics of incident waves incident to the metasurface and feeding back the electromagnetic characteristics to a microcontroller; and the microcontroller controls the voltage value of a PIN diode according to the electromagnetic characteristics so as to switch the working state of the metasurface. The working state comprises a communication state and a stealth state. The stealth state and the communication state can be switched in real time.

Description

technical field [0001] The invention relates to the field of stealth metasurfaces, in particular to an electromagnetic energy sensing intelligent stealth metasurface. Background technique [0002] Electromagnetic stealth, as a technology that prevents objects from being recognized by electromagnetic wave detectors or human eyes, has important research value in military, aerospace, marine and other technical fields. In the past two decades, the emergence of metamaterials and transformation optics has injected new vitality into the traditional field of electromagnetic stealth, and has quickly become a research hotspot in the field of electromagnetics in the 21st century. The current stealth technology is mainly divided into four categories: mimic stealth; hallucinatory stealth; wave-wrapping stealth; and wave-absorbing stealth. The traditional wave-absorbing stealth is mainly through the combination of coating the wave-absorbing layer on the surface of the object and the spec...
