Abstract
We show numerically that surface modes are associated with poles of th e scattering operator in the complex plane of wavelengths, which permi ts 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 l ocation of the poles of the scattering operator in the complex plane w as studied.
