Electromagnetic Problems Requiring High-Precision Computations

Abstract

An overview of the applications of multiple-precision arithmetic in CEM was presented in this paper for the first time. Although double-precision floating-point arithmetic is sufficient for most scientific computations, there is an expanding body of electromagnetic problems requiring multiple-precision arithmetic. Software libraries facilitating these computations were described, and investigations requiring multiple-precision arithmetic were presented. In particular, numerical-precision issues were demonstrated based on the example of the discrete Green's function. Finally, some open problems in electromagnetics were pointed out for further investigations.
