Three Dimensional Finite Difference Frequency Domain Scattering Computation Using the Control Region Approximation

Brian J. MCartin, John F. Dicello

Research output: Contribution to journalArticle


The Control Region Approximation is used to discretize the circuital form of Maxwell's equations thereby furnishing accurate electromagnetic scattering computations for complex three dimensional targets. Absorbing boundary conditions are generalized from spherical to rectangular parallelopiped outer boundaries thus providing an efficient computational procedure. An algorithm for the computation of broadband scattering characteristics in the frequency domain is presented.
