Efficient modeling of chiral media using SCN-TLM method

An efficient approach allowing to include linear bi-isotropic chiral materials in time-domain transmission line matrix (TLM) calculations by employing recursive evaluation of the convolution of the electric and magnetic fields and susceptibility functions is presented. The new technique consists to add both voltage and current sources in supplementary stubs of the symmetrical condensed node (SCN) of the TLM method. In this article, the details and the complete description of this approach are given. A comparison of the obtained numerical results with those of the literature reflects its validity and efficiency
