A theory of nonuniform dielectric media should prove valuable to people engaged in the design of antenna housings or radomes and to those designing absorbers. Such a theory is herein developed. The problem of inhomogeneous media is treated first by means of differential equations and then as a limiting case of an array of panels. Various equivalences such as behavior of a panel at arbitrary incidence angle with that at normal incidence are also discussed.
