Abstract

We present a multiple-scattering method in conjunction with supercell calculations to study the electromagnetic surface states in two-dimensional metallodielectric photonic crystals. In the case of dielectric photonic crystals with cylindrical scatterers, this method is able to produce surface states inside a partial or full gap for p-polarized waves, similar to those found previously by using the method of plane-wave expansion. However, in two different systems of metallodielectric photonic crystals we have studied here, we do not find surface states. This is true for both perfect metal and metal with a Drude-like dielectric function. The absence of surface states may be attributed to the expulsion of electric field from the surface into the homogeneous medium due to the presence of metallic component, making the formation of surface unfavorable.
