Abstract
Microwave oscillator using magnetostatic surface or bulk waves which can be transmitted in a thin layer of magnetic material having two cavity resonators with coupled gratings of different equivalent lengths in such a way that the first is multimode and the second monomode in the reflection pass band of the gratings, the cavities being arranged in such a way that the second filters the modes transmitted in the first. Microwave signals are applied to one of the two cavities and the resonated waves are collected in the second cavity.
