Abstract
A theoretical investigation is presented of the coupling between the backward wave propagating in a longitudinally magnetized yttrium-iron-garnet (YIG) rod enclosed in a cylindrical waveguide and the slow space-charge wave associated with the drift carrier stream in the semiconductor which contains diffusion and collision effects. These effects play an important part in the behavior of space-charge waves, but the slow wave always exists in ordinary semiconductors. When the drift carrier velocity has a value on the order of 5.106m/s, an effective coupling is easily obtained using a single-crystal YIG having a small linewidth.Keywords
