Singularity treatment and high-order RWG basis functions for integral equations of electromagnetic scattering
Various numerical techniques have been developed to carry out the electromagnetic Aeld simulation. They include mode matching method based on the eigenmode expansion of the computed object such as a cavity [1], Anite diDerence time-domain (FDTD) using Yee scheme [2], or integral equation formulation [3] with Galerkin-type approximation such as the method of moments (MOM) [4] or point matching m...
متن کاملA meshless technique for nonlinear Volterra-Fredholm integral equations via hybrid of radial basis functions
In this paper, an effective technique is proposed to determine thenumerical solution of nonlinear Volterra-Fredholm integralequations (VFIEs) which is based on interpolation by the hybrid ofradial basis functions (RBFs) including both inverse multiquadrics(IMQs), hyperbolic secant (Sechs) and strictly positive definitefunctions. Zeros of the shifted Legendre polynomial are used asthe collocatio...

متن کاملNumerical solution of nonlinear integral equations by Galerkin methods with hybrid Legendre and Block-Pulse functions
In this paper, we use a combination of Legendre and Block-Pulse functionson the interval [0; 1] to solve the nonlinear integral equation of the second kind.The nonlinear part of the integral equation is approximated by Hybrid Legen-dre Block-Pulse functions, and the nonlinear integral equation is reduced to asystem of nonlinear equations. We give some numerical examples. To showapplicability of...
متن کاملThe method of radial basis functions for the solution of nonlinear Fredholm integral equations system.
In this paper, An effective and simple numerical method is proposed for solving systems of integral equations using radial basis functions (RBFs). We present an algorithm based on interpolation by radial basis functions including multiquadratics (MQs), using Legendre-Gauss-Lobatto nodes and weights. Also a theorem is proved for convergence of the algorithm. Some numerical examples are presented...
