On the propagation of surface waves over an infinite grounded ferrite slab

A theoretical study is made of the propagation of surface waves along an infinite plane conductor coated with a layer of ferrite material subjected to a constant external magnetic field. For three directions of the external field, the electric and magnetic fields are computed for the separate media, and the relations between them arising from boundary conditions are expressed as transcendental equations. In the limiting case of small ferrite layer thickness (because of the loss problem of greatest physical interest), the fields and propagation constants may be expressed as simple closed forms.
