Abstract
Optimal symplectic integrators were proposed to improve the accuracy in numerical solution of time‐domain Maxwell's equations. The proposed symplectic scheme has almost the same stability and numerical dispersion as the mostly used fourth‐order symplectic scheme, but acquires more efficiency in the calculations at the same computational cost. © 2007 Wiley Periodicals, Inc.

An unconditionally stable precise integration time-domain method is extended to 3-D circular cylindrical coordinates to solve Maxwell's equations. In contrast with the cylindrical finite-difference time-domain method, not only can it remove the stability condition restraint, but also make the numeri
The Yee-method is a simple and elegant way of solving the time-dependent Maxwell's equations. On the other hand, this method has some inherent drawbacks too. The main one is that its stability requires a very strict upper bound for the possible time-steps. This is why, during the last decade, the ma
In this work, we present a new and efficient numerical method to sol¨e the coupled integral equations, deri¨ed utilizing the equi¨alence principle for arbitrarily shaped dielectric bodies, directly in the time domain. The solution method is based on the method of moments, and in¨ol¨es the triangular
We present a convergent high-order accurate scheme for the solution of linear conservation laws in geometrically complex domains. As our main example we include a detailed development and analysis of a scheme for the time-domain solution of Maxwell's equations in a three-dimensional domain. The full
