Analysis of square coaxial lines by using Equivalent Electrodes Method

In this paper the application of the Equivalent Electrodes Method (EEM) for the analysis of square coaxial lines has been presented. The capacitance per unit length, for different shapes and sizes, has been calculated. The results obtained by EEM have been compared with those reported in the literature, obtained by other methods, and those obtained by using software package COMSOL Multiphysics. These results have been found to be in very good agreement.

Mathematical Model of Major Hysteresis Loop and Transient Magnetizations

Abstract In this article, a new mathematical model of a major hysteresis loop and a simple procedure for the formation of first-order and higher-order reversal curves are proposed. The applicability of the model has been tested by comparison with measured results, obtained with electrical steel and ferrite cores, and simulation results obtained with the Preisach model. Very good agreement has been found between simulated and measured major and minor hysteresis loops, as well as first-order and higher-order reversal curves.
