New MoM code incorporating multiple domain basis functions

Abstract

A new method of moments (MoM) code is discussed. The code supports standard functionality, e.g. fully automatic re-meshing and variable’s assignment, ground plane and symmetry planes. In addition, the code realizes several new features. These include significant acceleration of the filling-in of the impedance matrix for high accuracy calculations on structures with redundancies, as well as realization of the multiple domain basis functions with a support for various aggregating basis function’s profiles, including piecewise linear and piecewise sinusoidal. New profiles may be easily defined. The current realization of the code has been tested on several references and showed an excellent match to the reference results.
