Abstract :
The author describes the capabilities and programming aspects of a typical finite-difference time-domain (FDTD) code for scattering and radiation analysis. The major functions of the code are discussed, and several examples are included, along with memory, CPU, and running-time information. FDTD has been around since the 1960s, but its application to complex composite geometries has primarily occurred during the past decade or so. The code described provides a look at the capabilities of modern FDTD codes.<>
