Abstract (en)
[origin: EP0769824A1] The device includes a cavity which is formed with a lateral transition part which is used for EM coupling of the input/output. The transitions (501) are formed by horns on the suspended substrate (55) around the perimeter of a printed conducting surface (50), abutting the respective transmission lines (502). Decoupling resistors are positioned between the horns and the cavity is designed for TEM mode propagation. A pair of dielectric discs (56,57) is stuck to either side of the substrate to determine a refractive index variation relation to obtain the propagation laws. The diameter of the discs matches that of the substrate and they are symmetric about the central plane. Their dielectric constant is greater than two and have a variable index to operate as a Luneberg lens.
