Abstract (en)
[origin: US4603311A] The invention provides electromagnetic resonators and high frequency filters constructed from these resonators which are formed by parallelepipeds made from a dielectric material, each of these parallelepipeds being covered with at least two metalizations disposed parallel to the direction of movement of an electromagnetic wave.
