“…6 and Table II show the convergence characteristics of the ICCG method and CPU-time in using the hybrid IEEMs with orthogonal expansion functions. For the RP-RL hybrid IEEM, we use the orthogonal expansion functions derived from RL formulation [6], [7]. On the other hand, for the RP-RL-RPL hybrid IEEM, we adopt the orthogonal expansions in Table I derived from RPL formulation.…”

The infinite edge element method (IEEM) has been proposed as an effective method for efficiently handling open boundary region, i.e., the air region. In this paper, we present a newly defined infinite element radiated from a reference plane (RPL), and propose the combination method using various infinite element configurations, such as radiated configurations from a reference point, a reference line, and an RPL. By using the proposed hybrid method, we can drastically decrease the number of ill-shaped infinite elements and improve the computational accuracy and convergence characteristics in comparison with the conventional IEEM, especially in the case of flattened analysis models. Index Terms-Finite element (FE) analysis, infinite edge element (IEE), open boundary, orthogonal expansion function, reference plane (RPL).
