An approximate K- pulse estimation technique based on Legendre polynomial expansions and late-time target response energy minimizations is formulated and applied to both high-Q and low-Q targets. The targets have varying degrees of geometrical complexity. The complex natural resonant (CNR) frequencies of the test targets are numerically extracted as frequency domain zeros of the resultant K- pulses. The validity of the K- pulse estimation results is demonstrated by means of target discrimination examples at arbitrarily chosen combinations of aspect and polarization. Comparisons of the extracted CNR frequencies with other results are also used to verify the K- pulse synthesis results wherever a priori information on a test target's natural resonances is available.

Multilevel fast multipole algorithm for the discrete dipole approximation Koc, S; Chew, WC (Informa UK Limited, 2001-01-01) The discrete dipole approximation, originally developed by Purcell and Pennypacker is a quite general method for solving scattering from irregularly shaped targets and/or a cluster of targets. Computationally, the method requires the solution of large dense systems of linear equations and various iterative methods have been employed in the literature for the purpose. In this work, the multi-level fast multipole algorithm is used to compute the matrix-vector product in the iterative methods. This algorithm h...
An efficient solution of the generalized eigenvalue problems for planar transmission lines Prakash, VVS; Kuzuoğlu, Mustafa; Mittra, R (Wiley, 2001-11-05) This paper presents an efficient solution for solving the generalized eigenvalue equation arising in the finite-element (FE) formulation of propagation characterization of planar transmission-line structures. A two-dimensional (2-D) finite-element method (FEM) is used for analyzing the uniform planar transmission lines. The Arnoldi algorithm is used in conjunction with the multifrontal decomposition of the system matrix for solving the eigensystem. Convergence is typically obtained within a few iterations o...
Forward-backward domain decomposition method for finite element solution of electromagnetic boundary value problems Ozgun, Ozlem; Kuzuoğlu, Mustafa (Wiley, 2007-10-01) We introduce the forward-backward domain decomposition method (FB-DDM), which is basically an improved version of the classical alternating Schwarz method with overlapping subdomains,for electromagnetic, boundary value problems. The proposed method is non-iterative in some cases involving smooth geometries, or it usually converges in a few iterations in other cases involving challenging geometries, via the utilization of the locally-conformal PML method. We report some numerical results for two- dimensional...
Analytical Solutions to the Klein-Gordon Equation with Position-Dependent Mass for q-Parameter Poschl-Teller Potential Arda, Altug; Sever, Ramazan; TEZCAN, CEVDET (IOP Publishing, 2010-01-01) The energy eigenvalues and the corresponding eigenfunctions of the one-dimensional Klein-Gordon equation with q-parameter Poschl-Teller potential are analytically obtained within the position-dependent mass formalism. The parametric generalization of the Nikiforov-Uvarov method is used in the calculations by choosing a mass distribution.
Numerical Constructions of Testing Functions for Improving the Accuracy of MFIE and CFIE in Multi-Frequency Applications Karaosmanoglu, Bariscan; Altinoklu, Askin; Ergül, Özgür Salih (EMW Publishing, 2016-01-01) We present a new approach based on numerical constructions of testing functions for improving the accuracy of the magnetic-field integral equation (MFIE) and the combined-field integral equation (CFIE) with low-order discretizations. Considering numerical solutions, testing functions are designed by enforcing the compatibility of the MFIE systems with the accurate coefficients obtained by solving the electric-field integral equation (EFIE). We demonstrate the accuracy improvements on scattering problems, wh...
