Abstract

We present a new numerical method, called the “field domain partition-combining solution,” for the analysis of complicated electromagnetic (EM) boundary-value problems (BVP). This is a numerical procedure based on the combination of the global numerical boundary condition (GNBC) and the finite-element method. Using this method, a variety of coaxial radiators can be precisely treated as BVP´s and rigorously solved for their “accurate global solution.” Three examples are given, demonstrating that the present numerical procedure is very general, flexible, and effective for both theoretical and engineering purposes
