Abstract :
An exact discretization procedure based on frame theory is presented and applied to integral equations resolution through a method of moments (MoM). The use of a Gaussian window function as basis element for the frame expansion allows for the representation of radiated fields as a superposition of shifted and rotated Gaussian beams. Numerical results are presented for a slot antenna at the interface between two dielectric half-spaces.
