Proceedings of the Thirteenth Annual Review of Progress in Applied Computational Electromagnetics
Concurrent engineering approaches for the disciplines of computational fluid dynamics (CFD) and electromagnetics (CEM) are necessary for designing future high-performance aircraft. A characteristic-based finite-volume time-domain (FVTD) computational algorithm, used by CFD and now applied toCEM, is implemented to analyze the radar cross section (RCS) of the ogive and cone-sphere. The technique utilizes a scattered-field formulation of the time-dependent Maxwell equations. The FVTD formulation implements a monotone upstream-centered scheme for conservation laws for the flux evaluation and a Runge-Kutta multi-stage scheme for the time integration. The results are obtained from the electromagnetic fields via a Fourier transform and a near-to-far field transformation.
