DEVICE USING DIELECTRIC LENS

摘要

[Problems] A dielectric lens able to be used in both radio wave band and light wave band, and a device using this dielectric lens. [Means of solving the problems] The device comprises a dielectric lens formed of a transparent dielectric member being small in dielectric loss and having an omni-directional feature to an electromagnetic wave, a transparent dielectric shell being hollow inside and having the radius of any one surface of this hollow shape that is equal to the focal distance of the dielectric lens, and a holding mechanism for positioning and holding the dielectric shell and the dielectric lens so as to locate the dielectric shell at a position along the focal distance with the dielectric lens included at the inner center of this dielectric shell. The device is provided at the focal point of the dielectric lens with a reflector for reflecting an electromagnetic wave or a generator for generating an electromagnetic wave.
