Dyadic Green's functions for SAW and leaky wave devices

The effective permittivity is widely used to compute the Green's function for SAW and leaky wave devices. In general, the effect of mass loading due to surface electrodes is ignored, and a single Green's function is obtained. In this paper, we examine a method, based on previous work by Adler and Peach, in which additional Green's function components describe the effects of T13, T23 and T33 stresses and the electrical displacement D on each of …
