High-Performance Conformal FDTD Techniques

In this article we have presented the major features of the parallel conformal FDTD method and its applications to the electromagnetic simulation of microwave devices and components. We have used the parallel conformal FDTD code and have run it on parallel platforms to simulate a number of representative problems that find important engineering applications. We verified the performance of the parallel FDTD code when applied to these problems and demonstrated that the parallel conformal FDTD code not only exhibits excellent parallel efficiency, but also provides savings in computer memory usage when compared to other codes that are based on similar algorithms. The combination of these two features enables the parallel conformal FDTD code to simulate large, complex and practical problem geometries in a time-efficient manner.
