An application of singularity cancellation for periodic structures in free space

Adanir, Süleyman
Alatan, Lale
A singularity problem arises in the computation of MoM matrix entries. Several singularity cancellation schemes are proposed in literature. One of these singularity cancellation methods is applied to handle the singularity problem associated with the MoM analysis of 2D periodic structures. For the efficient computation of the 2D periodic Green's function, Ewald transformation is used, resulting in a change in the kernel of the integral associated with the MoM matrix entries. Formulation of the problem for this new kernel is presented together with numerical results for a sample problem.

A method for chromosome handling of r-permutations of n-element set in genetic algorithms
Üçoluk, Göktürk (1997-04-16)
Combinatorial optimisation problems are in the domain of Genetic Algorithms (GA) interest. Unfortunately ordinary crossover and mutation operators cause problems for chromosome representations of permutations and some types of combinations. This is so because offsprings generated by means of the ordinary operators are of a great possibility no more valid chromosomes. A variety of methods and new operators that handle that sort of obscenities are introduced throughout the literature. A new method for represe...
An error analysis of iterated defect correction methods for linear differential-algebraic equations
Karasözen, Bülent (1996-01-01)
Asymptotic expansions of the global error of iterated defect correction (IDeC) techniques based on the implicit Euler method for linear differential-algebraic equations (dae's) of arbitrary index are analyzed. The dependence of the maximum attainable convergence order on the degree of the interpolating polynomial, number of defect correction steps, and on the index of the differential-algebraic system is given. The efficiency of IDeC method and extrapolation is compared on the basis of numerical experiments...
A Modal Superposition Method for the Analysis of Nonlinear Systems
Ferhatoglu, Erhan; Ciğeroğlu, Ender; Özgüven, Hasan Nevzat (2016-01-28)
In the determination of response of nonlinear structures, computational burden is always a major problem even if frequency domain methods are used. One of the methods used to decrease the computational effort is the modal superposition method for nonlinear systems where the modes of the linear system are used in the calculation. However, depending on the type of the nonlinearity, in order to obtain an accurate response, the number of modes retained in the response calculations needs to be increased, which i...
A Novel Approach for the Efficient Computation of 1-D and 2-D Summations
Karabulut, E. Pinar; ERTÜRK, VAKUR BEHÇET; Alatan, Lale; Karan, S.; Alisan, Burak; Aksun, M. I. (2016-03-01)
A novel computational method is proposed to evaluate 1-D and 2-D summations and integrals which are relatively difficult to compute numerically. The method is based on applying a subspace algorithm to the samples of partial sums and approximating them in terms of complex exponentials. For a convergent summation, the residue of the exponential term with zero complex pole of this approximation corresponds to the result of the summation. Since the procedure requires the evaluation of relatively small number of...
On construction of recursion operators from Lax representation
Gurses, M; Karasu, Atalay; Sokolov, VV (1999-12-01)
In this work we develop a general procedure for constructing the recursion operators for nonlinear integrable equations admitting Lax representation. Several new examples are given. In particular, we find the recursion operators for some KdV-type systems of integrable equations. (C) 1999 American Institute of Physics. [S0022-2488(99)03212-0].
