Abstract :
A novel split-field alternating-direction implicit method is proposed to simulate two-dimensional transverse-magnetic waves in lossy media. By splitting the electric field with respect to the two transverse-magnetic field components, an efficient implementation scheme is obtained. Stability and numerical dispersion are further examined. Finally, numerical examples demonstrate the validity of the proposed method.
