Abstract
A radio wave control system includes a phase adjustment plate that transmits a radio wave from a second main surface to a first main surface and focuses the radio wave on a focal point; and a reflection plate installed at a position irradiated with the radio wave transmitted through the phase adjustment plate.
Claims13
A radio wave control system comprising:
- a phase adjustment plate that transmits a radio wave from a second main surface to a first main surface and focuses the radio wave on a focal point;
- and
- a reflection plate installed at a position irradiated with the radio wave transmitted through the phase adjustment plate,
- the reflection plate is installed at a position satisfying
- (P×S)/(P0×S0)>1,
- where P is a value obtained by integrating power of the radio wave transmitted through the phase adjustment plate on the reflection plate, S is an area of a half-power plane on the reflection plate, P0 is a value obtained by integrating power of the radio wave transmitted through the phase adjustment plate on the reflection plate in a case where the phase adjustment plate is not provided, and S0 is an area of a half-power plane on the reflection plate in the case where the phase adjustment plate is not provided, and
- wherein the reflection plate is disposed at a position separated from the focal point of the phase adjustment plate by 7% or more of a focal length of the phase adjustment plate.
