Abstract
The paper reports a new phenomenon of a spatial synchronism of electromagnetic waves propagating in a transmission line and magnetostatic waves excited in a ferrite layer (film). This synchronism results in the extremely narrow (less 1°) radiation pattern of magnetostatic wave antennas and in the unidirectional propaption of magnetostatic wave beams at certain frequencies. Application of the effect is suggested for space filtering of magnetostatic waves and for tunable microwave multichannel filters.
