Abstract

The invention discloses a fully enclosed rectangular terahertz darkroom. The material used for the wall of the darkroom is a three-dimensional skeleton nickel material, which can not only realize high-efficiency and high-bandwidth absorption of terahertz waves, but also has simple and cheap processing and strong practicability; Shielding of external terahertz waves; capable of suppressing leakage of internal terahertz waves; capable of greatly attenuating reflection and scattering of internal terahertz waves.

Description

technical field [0001] The invention belongs to the technical field of terahertz wave stealth and shielding, and in particular relates to a fully enclosed rectangular terahertz darkroom. Background technique [0002] The electromagnetic wave anechoic chamber is an electromagnetic measurement environment close to free space. It can suppress the multipath reflection interference of internal electromagnetic waves and shield external electromagnetic interference by absorbing as much electromagnetic waves as possible. With the rapid development of science and technology, the electromagnetic environment in space is becoming more and more complex, and the influence of various electromagnetic equipment on each other is increasing. The test of electromagnetic wave equipment in open space is due to the interaction between electromagnetic waves. Inaccurate. At present, the technical means and design schemes of electromagnetic wave anechoic chambers in the microwave frequency band are ...
