Used FDTD method with PML and Mur ABC to calculate effective dielectric constant

Abstract

The absorbing boundary conditions (ABCs) are essential to terminate the computational space when the finite difference time-domain (FDTD) method is applied to analyze electromagnetic (EM) problems. In this paper, we used two kinds of ABCs to calculate effective dielectric constant of a microstrip. The comparison of these results has shown the advantage and disadvantage of these two ABCs.
