  It has been discovered that heterostructure bicrystal arrangements lead to
field asymmetry in guided wave structures. Here a study is conducted over a
range of nominal permittivity values to see if the effect is present in widely
varying dielectric materials. Marked shifts of the field distribution occurs in
some cases, and this can be the basis of an all electronic isolator. Such an
all electronic device could be fixed or even constructed as a control component
using materials with electrostatically controllable permittivity. Distributions
have been obtained to demonstrate the effect using an anisotropic Green's
function solver.
