Method and structure for installing pyramid wave-absorbing material at wall internal corner

Abstract

The invention relates to a method and structure for installing a pyramid wave-absorbing material at a wall internal corner. The installing method includes the steps that the angle theta of the indoor wall internal corner is measured, two identical pyramid wave-absorbing material pieces are taken, the sides, needing to be spliced, of the two pyramid wave-absorbing material pieces are cut at the cutting angle of 90-1/2*theta, the cutting surfaces of the two cut pyramid wave-absorbing material pieces are spliced, and the two cut pyramid wave-absorbing material pieces are pasted on the two sides of the wall internal corner. According to the installing structure, the two identical pyramid wave-absorbing material pieces comprise the cutting surfaces with the angle of 1/2*theta, and the two pyramid wave-absorbing material pieces with the cutting surfaces spliced are pasted on the two sides of the wall internal corner, wherein theta is the angle of the wall internal corner. The method and the structure solve the problem that a pyramid wave-absorbing material cannot be effectively installed at a wall internal corner, and the electrical property of a microwave chamber is improved.

Description

technical field [0001] The invention belongs to the field of microwave anechoic chamber construction, in particular to the field of installation of pyramidal wave-absorbing materials in the microwave anechoic chamber. Background technique [0002] In the indoor testing of antenna, radar and other wireless communication, measurement or other electronic products, it is necessary to establish an artificial "free space" environment without electromagnetic reflection. It is common practice to construct a microwave anechoic chamber to obtain the test conditions required above. Pyramid absorbing materials are pasted on all the walls inside the microwave anechoic chamber to absorb the energy of electromagnetic waves from the emission source, suppress the reflection of electromagnetic waves well, and form a "free space" with almost no electromagnetic reflection. However, when the pyramid absorbing material is pasted on the inner corner of the indoor wall, the pyramid interferes with...

AI Technical Summary

Problems solved by technology

However, when the pyramid absorbing material is pasted on the inner corner of the indoor wall, the pyramid interferes with each other, resulting in a small area of ​​the inner corner of the wall that cannot be pasted with the absorbing material

In the past, the flat absorbing materials in the shape of wall bricks were pasted or exposed directly without pasting any materials, which affected the performance of the microwave anechoic chamber.
