Random rough surfaces: numerical study of localized electromagnetic surface modes.
We show numerically that surface modes are associated with poles of the scattering operator in the complex plane of wavelengths, which permits one to excite a mode strongly in such a way that the amplitudes of the incident wave and of the waves scattered in the air are negligible. Then the shape of the surface mode clearly appears, and localization effects are well isolated. The influence of Bragg resonances on the location of the poles of the scattering operator in the complex plane was studied.
