Abstract :
An analysis is presented for modes propagating via a periodic metal grating on the surface of a piezoelectric substrate. Assuming no loss in the structure, the numerical solution is exact in the limit, combining the effective permittivity function formulation with the least-squares residual applied at the surface.
