Abstract
The Characteristic Basis Function Method (CBFM) and its variants are designed to solve large-scale electromagnetic problems numerically efficiently with limited computing resources. CBFM enables the user to set an upper limit on the size of the matrix equation that must be inverted when modelling a variety of electromagnetic problems. The CBFM is free from the primary memory constraints of the available computing machines and avoids the use of any iterative method. The CBFM is easily parallelisable and is especially suitable for shared memory implementations. Perfect electrical conductors (PEC) are quite successfully modelled using the CBFM. This contribution investigates the use of the CBFM for the problem of computing the electromagnetic (EM) fields inside dielectric objects. Two versions of the CBFM suitable for dielectric objects are presented. Numerical results are summarised to demonstrate the efficacy of the CBFM for EM analysis of dielectric objects.
