Hybrid Integral Equation and Finite Difference Method for Low-Frequency Electric Induction

Abstract

Recently developed fast integral equations solution methods allow for the treatment of electrostatic problems involving perfect conductors of complicated shape. Using the precepts of Stevenson's method, external electrostatic solutions can be used in the solution of internal low frequency electric induction problems in electrically small isolated compact conducting bodies. A precorrected FFT algorithm is implemented to solve the electrostatic problem of an isolated human body situated in an external field. The resulting induced fields. It is shown that the resulting hybid cody produces results that are in excellent agreement with those produced by other methods, while being significantly more effiecient in terms of computer memory and time resources
