Abstract
In this paper, we develop broadband Green's functions for inhomogeneous waveguide with arbitrary shaped boundary using Broadband Green's function with low wavenumber extraction (BBGFL). The waveguide consists of two dielectrics and a linear eigenvalue problem is obtained for the modal solution by using surface integral equations and broadband Green's functions of the reference waveguide. The modes are calculated and are independent of frequency. The broadband Green's functions of the inhomogeneous waveguide is next expressed as a summations of these modes. The convergence of modal summations is accelerated by low wavenumber extractions. The accuracy of the results are verified by comparison with results from direct method of moment (MoM) and HFSS.
