Abstract

The invention provides a wave absorbing body structure comprising a metal base plate and an electrical loss body covering one surface of the metal base plate. Since the electrical loss body has a high dielectric loss, the wave absorbing body structure of the present invention has a good wave absorbing effect in a wide frequency band compared with the absorbing performance of the wave absorbing material of a conventional low-loss multi-layer wave absorbing honeycomb. With the structure of the invention, not only the wave absorbing performance can be increased, but also a low surface density can be achieved for the structure due to the reduced overall thickness of the structure; accordingly, the wave absorbing body structure can be applied in fields requiring bearing and weight reducing.

Description

technical field

[0001] The invention relates to a wave absorber, in particular to a wave absorber structure. Background technique

[0002] According to the structure and shape, the absorbing materials can be divided into film absorbing materials, flat absorbing bodies, pyramid or wedge absorbing bodies, honeycomb absorbing bodies and so on. Absorbing materials not only require excellent absorbing performance, but also require other properties such as weight, thickness, and bandwidth according to different uses. Therefore, it cannot be expected that one design method can meet all performance requirements.

[0003] The absorber structure is an important means of obtaining light-weight broadband absorbing materials. It is generally made of low-density, low-permittivity dielectric materials and resistors. The resistance of the resistors gradually decreases from the surface to the ground metal plate. , by changing the effective impedance along the thickness direction of the abso...
