摘要：
High-frequency properties of a "waveguide comb" periodic structure whose comb plates are manufactured from a magnetic superlattice exhibiting the giant magnetoresistive effect are investigated. It is shown that the transmission coefficient of this periodic structure can be controlled by an external magnetic field that changes the resistivity of this superlattice. Experiments performed in the millimeter wave band on a periodic structure whose comb plates are made of an Fe/Cr superlattice have shown that the periodic structure substantially increases the efficiency of interaction between waves and the superlattice. Under the action of an external magnetic field, the magnitude of the transmission coefficient of the periodic structure with a superlattice increases to 50%.
