The Spherical Harmonic Interface Procedure for MM and UTD CodesAbstract
This paper describes the use of a spherical harmonic expansion as an efficient interface between a low frequency method of moments (MM) code and a high frequency uniform geometrical theory of diffraction (UTD) code. It is shown that the method can save significant CPU time in the UTD code provided that the number of MM current filaments per cubic wavelength is large.
