Abstract :
This paper describes a novel formulation for the description of thin wires in coarse numerical models. The approach is based upon exact field expansions around a thin wire which are then interfaced with the numerical algorithm; here the transmission line modeling (TLM) numerical method is used The new formulation yields a robust, accurate and stable simulation method that allows for variable wire radii and arbitrary positioning within numerical cells without the use of empirical factors. Significantly, it also does not incur additional overhead in terms of hardware or simulation run time. Numerical examples are given which indicate the suitability of the method for application in Electromagnetic Compatibility (EMC) problems.
