Abstract: This paper describes EM Wave Simulation, a windows-based animated electromagnetic wave simulation package, developed as a supplementary tool for teaching electromagnetic field theory at the undergraduate level. For the purpose of rapid display of electromagnetic wave images, the implemented algorithm assumes a structure sandwiched between two perfect electric conductor planes and employs a 21/2-dimensional finite-difference time-domain (FDTD) method on a staggered grid, which is suitable for simulating simplified electromagnetic wave propagation in indoor environments. Frequency-domain spectral information can be extracted with the built-in one- and two-dimensional discrete Fourier transforms facilities. A user-friendly mouse-and-menu-driven interface allows user to set up simulations containing complex geometries in a straightforward fashion. Simulated results, in both time and frequency domains, can be displayed in real-time on the computer screen, which makes the application ideal for use in interactive undergraduate teaching. Some sample simulations are discussed in the paper to illustrate its principal functionality.
