Abstract :
An experimental and theoretical study is presented of the insertion loss of magnetostatic surface wave delay lines. The magnetostatic surface waves are excited by single microstrip transducer and propagate in a delay line consisting of conductor-dielectric-YIG-GGG. The effect of nonuniformity in microstrip current and the effect of finite width of YIG film are included in the theory. An undesired notch seen in the insertion-loss response of the surface-wave delay line in the low-frequency region of the band is explained by the present theory, which includes the finite width of the YIG film
