Abstract

An approximate method for determining the statistical properties of an FDTD Analysis has been derived, allowing the determination of the mean and the variance of an FDTD simulation. This stochastic simulator progresses in the same fashion as an FDTD simulation progresses. The variance-wave builds and propagates with reflections occurring at dielectric boundaries. Computer overhead is reduced, i.e. memory and runtime are substantially reduced. Permitting the statistics, i.e. mean and variance to be determined without spending allot of time and computer resources for performing Monte Carlo analysis. This would allow the industry to look at statistical analysis in large 3D model spaces using FDTD, which currently is not being done.
