Abstract

New simulation technique, by the transmission line matrix method(TLM), of electromagnetic waves in dispersive cold plasma media is proposed. This technique exploits the dependence of the current density J and the electric field E, and the derivation of the ordinary differential equations (ODE) by the exponential fitting method. The TLM Model uses the standard symmetrical condensed node(SCN) with 12 principal ports and 3 additional ports in which we incorporate voltage sources to model the dispersive behavior of cold plasma media. To investigate the accuracy of this approach, reflection and transmission coefficients of non-magnetized plasma wall are computed. Also the far-zone scattering results of a cold plasma sphere are presented. All the obtained results, using the new modeling technique named JE-TLM are in good agreement with those of the theoretical ones.
