Paper Abstract

Based on an exact solution of the pertinent boundary-value problem, a method is presented for finding the electromagnetic fields scattered or guided by dielectric gratings having arbitrary profiles. This method unifies the treatment of both perpendicular (TE) and parallel (TM) polarization by using the Boundary Element Method (BEM). To illustrate the method, the results are presented for a four layer waveguide with trapezoidal grating.
