Abstract
The invention relates to a dielectric lens useable in both the radio wave band and the light wave band, and a device using this dielectric lens. The device comprises a dielectric lens formed of a transparent dielectric member small in dielectric loss and having an omnidirectional feature with regard to an electromagnetic wave, a transparent dielectric shell that is hollow inside and having the radius 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.
