Finite-Difference Time-Domain Algorithm for Scattering from Plane-Wave Source
A two-dimensional finite-difference time-domain (FDTD) algorithm is used to generate a total-field/scattered-field plane-wave source. The generated plane wave is in the transverse magnetic mode (TM). This Demonstration shows the time evolution of the nonzero field components , and ) of the electromagnetic wave.
