Research of the indoor reflection wave control with phase control wall

In this paper, the effect when the reflector that can control the reflection wave phase is installed on the room wall is reported though it is a planar shape. Concretely, it is thought that the wall approximate to the parabolic surface if the phase of the reflection wave is delayed near the center of the wall. Hence, the planar phase delay element loading to room wall is proposed in this paper. Moreover, diffusion is also possible if concentrating is possible. It is thought that the problems of an indoor microwave fading are also solvable by this technique. The following chapter explains these concepts in detail.
