Abstract
A model is proposed for the propagation of magnetostatic surface waves in a layered structure consisting of a ground plane and a YIG film separated by a dielectric. The standard assumption of an infinite sample width is replaced with an assumption of a sinusoidal transverse distribution of rf fields. Instead of a single solution, a multiplicity of solutions is found, each with a distinct dispersion relation. Experimental observation of the first two finite‐width modes is in excellent agreement with predicted results derived from the model.Keywords
