Abstract

A method is shown for the computation of the insertion loss of magnetostatic-surface wave transducers. In the first step of the method, a closed-form expression is derived for the solution of the telegrapher´s equations for the microstrip transducers. The insertion loss is then obtained from this solution as a function of three transmission line parameters, i.e., the propagation constant and the characteristic impedance of the YIG-loaded microstrip line and the mutual inductance between the two microstrips. In the second step, these transmission line parameters are numerically computed by applying a full-wave method of moments technique. The theoretical results obtained have been found to be in good agreement with experimental results.
