Accurate global solutions of EM boundary-value problems for coaxial radiators

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.<
