WAVE ABSORBING WALL - TAISEI CORP

Title:

WAVE ABSORBING WALL

Document Type and Number:

Japanese Patent JPH10224076

Kind Code:

A

Abstract:

To provide a wave absorbing wall having a large plane shape, thin, light and appropriate for false image prevention measures for aerial raders.

Reinforcing bars 12 as reflecting members are attached to the rear of a first glass fiber containing mortar board 10, and are short-circuited. To the first glass fiber containing mortar board 10, 60wt.% of Mn-Zn ferrite powder (powder diameter 0.6mm or smaller) is added and formed into a platy shape by spraying. Then, a wave absorbing wall having an excellent absorbing property in 1GHz band can be constituted. As compared with a ferrite tile, it is possible to mass-produce first glass fiber containing mortar boards 10 of larger shapes. And it becomes possible to obtain thinner and lighter ones, since thick concrete is unnecessary unlike before.
