    Abstract

    Electromagnetic phenomena intrinsically spread over an infinite region. Thus, effcient handling of open boundaries is one of the main issues in electromagnetic feld computations. This paper deals with the orthogonalized infinite edge element method that effciently performs precise analysis of the infinite region. In this method, several parameters are used to achieve high accuracy. As one of the parameters, we focus on the reference point and investigate the effect of its position setting on accuracy. We also evaluate the accuracy of the calculated magnetic feld in the far region. By applying boundary element method as postprocessing, it is found that high computational accuracy in the region can be effectively achieved.
