New Basis Functions for the Electromagnetic Solution of Arbitrarily-shaped, Three Dimensional Material Bodies Using Method of Moments

We present two sets of basis functions, defined over a pair of planar triangular patches, for the solution of electromagnetic scattering and radiation problems associated with arbitrarily-shaped conducting/dielectric surfaces using the method of moments solution procedure and triangular patch modeling. The basis functions are constant over the function subdomain and resemble pulse functions in one and two dimensional problems. Further, these two sets of basis functions are point-wise mutually orthogonal. The primary objective of developing these basis functions is to utilize them for obtaining a stable and robust electromagnetic solution involving conducting, dielectric, and composite bodies.
