Broadband Green's function with higher order extractions for arbitrary shaped waveguide obeying Neumann boundary conditions

Abstract

The broadband Green's function with low wavenumber extraction (BBGFL) consists of low wavenumber method of moments (MoM) solutions combined with modal representations of Green's functions. BBGFL is suitable for broadband simulations because the modal functions are independent of frequencies. In this paper, we extend the formulation of the higher-order extraction method (sixth-order convergence) to an arbitrarily-shaped homogeneous waveguide obeying Neumann boundary conditions. Results from BBGFL are in good agreement with those computed by direct MoM and HFSS. This method can be applied to exact, fast and broadband computation of multiple resonant frequencies and modes of arbitrarily-shaped PCB power/ground planes.
