Abstract

A set of two-dimensional (2D) electromagnetic (EM) MATLAB codes, using both first-order coupled differential (Maxwell) equations and second-order decoupled (wave) equations, are developed for both transverse-magnetic (TM) and transverse-electric (TE) polarizations. Second-order MUR type absorbing boundary conditions are used to simulate free space. Metamaterial (MTM) modeling is also included. Performance tests in terms of computational times, memory requirements, and accuracies were done for simple EM scenarios with magnetic field, current, and voltage comparisons. The codes may be used for teaching and research purposes.
