Abstract :
The propagation of electromagnetic surface waves in a metallised ferrite¿dielectric sandwich is described. The computed dispersion curve is found to be critically dependent on the dielectric-slab thickness. The theoretical results are illustrated by measuring the direct and reverse r.f. transmission through a polycrystalline y.i.g. slab as functions of the frequency.
