Abstract

An embodiment of the present invention provides a wave-absorbing and wave-transparent super material structure and an aircraft. The structure comprises at least one first microstructure array, at least one second microstructure array and a first dielectric layer, the at least one first microstructure array, the first dielectric layer and the at least one second microstructure array are stacked inorder. Each first dielectric microstructure array comprises multiple wave-absorbing microstructures, and each second microstructure array comprises multiple wave-transparent reflection microstructures. The structure has high wave-absorbing performance for incident electromagnetic waves in an X band and a Ku-band or the X-band and has high wave-transparent performance for incident electromagnetic waves in a P band.

Description

technical field [0001] The invention relates to the field of electromagnetic waves, in particular to a wave-absorbing metamaterial structure and an aircraft. Background technique [0002] Radar is currently one of the most effective means to find air targets, so the radar cross section (Radar Cross Section, RCS) of the aircraft itself is an important factor affecting the survival and penetration capabilities of the aircraft itself. Most of the existing aircraft use radome with combination of stealth shape and stealth paint or stealth shape and frequency selective surface to solve the RCS problem of the antenna. However, the former needs to spend a lot of time and cost maintenance, and the latter has been discovered after the dual (multi) station radar began to appear. [0003] At present, common schemes mostly adopt the combination of various functional layers of square periodic structure to realize the integrated function of absorbing and transmitting waves. This kind of ...
