Time-domain scattering simulations using a high-order overset-grid approach
A parallel, high-order, overset-grid method is used to solve Maxwell’s equations in the timedomain. The approach utilizes high-order spatial differencing and filtering formulas, coupled with a fourth-order, explicit temporal algorithm. For demonstration and validation purposes, this approach is used to simulate plane-wave scattering from a perfect electrical conducing sphere. The method was found to be very accurate compared to 2nd-order FD/TD methods and shows great promise for predicting the scattering of high-frequency waves by complex shapes.
