Microstrip Propagation on Magnetic Substrates - Part II: Experiment

Abstract

Experimental data taken on microstrip built on ferrite and garnet substrates are presented and compared with theoretical values calculated from formulas derived in a previous paper which were extended to gyromagnetic media. Good agreement has been obtained between experiment and theory. In particular the observed increase in wave attenuation at frequencies near /spl omega//sub m/ is fully explained when the frequency dependence of the characteristic impedance is taken into account.
