Abstract :
This article focused on the vector two-dimensional finite-difference time-domain (V2-D FDTD) method for axisymmetrical devices, also known as BOR FDTD. The approach to solving Maxwell equations by the V2-D FDTD method is straightforward. Not only the whole structure simulation is feasible, facilitating a search for globally optimum solutions, but also a valuable insight is provided into the subtleties of the device operation in the 3-D space and time. A graphical interface of the QW-V2D solver has been used to exemplify how the software helps in problem solving and quick search for new solutions.
