The influence of an infinite set of waveguides on the evanescent field of a surface plasmon excited at attenuated total reflection by a Gaussian beam is studied theoretically. The set of waveguides is treated as a periodic inhomogeneous medium, with period a. Numerical results are presented for the case when a is greater than l, the wavelength used to excite the surface plasmon. This case leads to the simulation of Scanning Tunnel Optical Microscopy in 2D geometry.
