Boundary integral equations IEs are an accurate and versatile tool in the electromagnetic scattering by smooth cylinder 1 especially when it is combined with analytical preconditioning 2. An original approach to the E-wave scattering by PEC polygons was developed in 3 to study a triangular prism. Here the boundary of the scatterer was conformally mapped on a circular cylinder 4, and a log-singular IL was treated by a simple moment method. We combine this idea with the method of analytical regularization MAR and study the scattering by triangular dielectric cylinders. Applications of this analysis are expected in the design of microwave and optoelectronic prism sensors and couplers.
