Abstract :
In this work we have extended the applicability of the GMM to a wide range of arbitrary geometries. The basis functions show excellent approximation qualities for the current, its curl and its divergence. In addition, the use of the surface Helmholtz decomposition results in a well conditioned system of equations over a wide range of frequencies. Future work is directed at fully utilizing these two advantages to the analysis of multi-scale geometries and a wide array of practical problems.
