Description

technical field

[0001] The invention belongs to the field of design and preparation of frequency modulation stealth materials and structures, and in particular relates to a graphene / polymer new composite structure electromagnetic stealth board with adjustable frequency absorbing stealth performance. Background technique

[0002] High-performance electromagnetic stealth materials (materials with strong absorption and weak reflection functions for electromagnetic waves) are in urgent demand in the fields of detection, communication, aerospace, aviation, and advanced equipment. Electromagnetic stealth technology uses electromagnetic stealth materials and structures to weaken, suppress, absorb, and deflect the intensity of electromagnetic waves to minimize the probability of (radar electromagnetic wave) detection system discovering and identifying (detecting targets). With the development of the information age, high-performance electromagnetic stealth materials have huge applic...
