Characteristic basis function method for solving electromagnetic scattering problems over rough terrain profiles
Yagbasan, A.; Tunc, C. A.; Erturk V. B.; Altintas, A.; Mittra, R. (IEEE, 2010-3-1)A computationally efficient algorithm, which combines the characteristic basis function method (CBFM), the physical optics (PO) approach (when applicable) with the forward backward method (FBM), is applied for the investigation ... -
Choices of expansion and testing functions for the method of moments applied to a class of electromagnetic problems
Aksun, M. I.; Mittra, R. (IEEE, 1993-03)It is well known that the choice of expansion and testing functions plays an important role in determining the rate of convergence of the integrals associated with the moment method matrix, and that an improper choice can ... -
Closed-Form green's functions and their use in the method of moments
Aksun, M. Irsadi; Mittra, R. (World Scientific Publishing Company, 1996)Derivation of the spatial-domain, closed-form Green's functions of the vector and scalar potentials are demonstrated for planar media, and their use in conjunction with the method of moments (MoM) is presented. As the ... -
Derivation of Closed-Form Green’s Functions for a General Microstrip Geometry
Aksun, M.I.; Mittra, R. (1992)The derivation of the closed-form spatial domain Green’s functions for the vector and scalar potentials is presented for a microstrip geometry with a substrate and a super-state, whose thicknesses can be arbitrary. The ... -
