Abstract

In this paper, a new approach for analyzing multilayered waveguide bends using an integral equation technique is introduced. The equivalence principle is employed to form a combined field integral equation (CFIE). The use of complex images Green´s functions in the method of moments solution of the developed CFIE formulation results in a highly accurate and fast solution of the problem and simultaneously, reduces computational complexity. The proposed method is applied to a general 2-D optical bend. The accuracy of the results is verified by comparison with the physical optics method.
