TL;DR: In this paper, a simplified version of the original nonlinear lumped network (NL/sup 2/N)-FDTD approach is presented, which does not require a complicated precalculation and a huge back-storage compared to the former version.
Abstract: In this letter, we present an efficient and simple reduced nonlinear lumped network (RNL/sup 2/N)-FDTD method for the global modeling of RF and microwave circuits. This method is a simplified version of the original nonlinear lumped network (NL/sup 2/N)-FDTD approach, which does not require a complicated precalculation and a huge back-storage compared to the former version.

TL;DR: In this paper, an efficient approach allowing to include linear bi-isotropic chiral materials in time-domain transmission line matrix (TLM) calculations by em- ploying recursive evaluation of the convolution of the electric and magnetic fields and susceptibility functions is presented.
Abstract: An efficient approach allowing to include linear bi-isotropic chiral materials in time-domain transmission line matrix (TLM) calculations by em- ploying 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 de- scription of this approach are given. A comparison of the obtained numerical re- sults with those of the literature reflects its validity and efficiency.

TL;DR: The propagation constant of a microstrip line in the interface of one dielectric is computed as a function of different shape characteristics and some numerical results are shown, obtained with analyzing this structure in a large band of frequencies.
Abstract: In this paper, we present a full-wave analysis of microstrip lines printed on variable thickness substrates using the method of lines (MoL). The propagation constant of a microstrip line in the interface of one dielectric is computed as a function of different shape characteristics. The results are compared with those obtained in previous research, especially with those using the discrete mode matching technique (DMM). Good agreement is found between the results. Furthermore, the convergence behavior of the method of lines is examined and finally, we show some numerical results, obtained with analyzing this structure in a large band of frequencies.
