Transients on a loss less exponential transmission line with a pure resistance load are presented in this paper. The approach is based on the two-port presentation of the transmission line. Using Picard-Carson's method the transmission line equations are solved. The relationship between source voltage and the load voltage in s-domain is derived. All the results are plotted using program package Mathematica 3.0

As reported in the open literature, there are many memristor models for the circuit-level simulations. Some of them are not particularly suitable for microwave circuit simulations. At RF/microwave frequencies, the memristor dynamics become an important issue for the transition process. In this paper we present a number of different SPICE memristor model groups. Each group is explained using representative models, which are analysed and compared from the microwave circuit analysis viewpoint. We consider the model behaviour at RF/microwave frequencies and the memristance setting issues. Results are compared and the best models are recommended.

Two different approaches for homogeneous electrical field generation are presented in this paper. For this generation a primary cell which consists of toroidal electrodes is used. Potential distribution along the system axis is expanded into Taylor and Chebyshev series in the first approach. System dimensions are chosen by setting corresponding terms to zero value so that only linear term remains. In the second approach the synthesis of systems with axial potential linear distribution is performed. Optimization of the electrodes parameters was carried out using gradient method. A deviation of electric field intensity is used as a criterion of the level of obtained homogeneity.
