Abstract
Content

A method of massively parallel computation on supercomputers has been developed to facilitate numerical simulation of electromagnetic fields in the vicinities of electrically large and complex radiating and scattering objects. In this method as in methods developed previously for the same purpose, Maxwell’s equations are solved by use of finite-difference approximations in both space and time. However, unlike in the other methods, this method is not limited to implicit (and thus parallel) solution in space with explicit (and thus sequential) time stepping with small time steps to ensure numerical stability. Instead, this method provides for parallel solution for all time steps, and the time steps can be larger and thus fewer — this characteristic is often characterized in the literature as “coarse-grained parallelism.”
