Wave absorber for tile and how to install them and design method, wave absorption panels, radio wave absorption structures, tunnel interior plate and unnecessary radio waves reflection suppression method

摘要

PPROBLEM TO BE SOLVED: To provide an incombustible tile for electromagnetic wave absorption, which can exert an electromagnetic wave absorption function, reflects much light, and is fit to be provided in a structure. PSOLUTION: This tile 10 for the electromagnetic wave absorption, which is composed of a material including an electromagnetic wave absorption material, is equipped with an incombustible electromagnetic wave absorption layer 11 which comprises a first surface 11a undergoing the incidence of an electromagnetic wave, a second surface 11b on the other side of the first surface 11a, and a side surface 11c for coupling the first and second surfaces 11a and 11b together. The tile 10 is also equipped with a light reflection layer 12 which is arranged in such a manner as to cover the first surface 11a of the layer 11, which protects the layer 11, and which reflects the light. The tile 10, which is wholly formed in a plate-like shape, exerts the electromagnetic wave absorption function when an electromagnetic wave reflection layer is arranged in such a manner as to face the second surface 11b of the layer 11.
