Electromagnetic (EM) problems with complex media are formulated by volume integral equations (VIEs) in the integral equation approach. The VIEs are usually solved by the method of moments (MoM) with the Schaubert-Wilton-Glisson (SWG) basis function, but the solution requires high-quality conforming meshes, resulting in a high cost in geometric discretization. In this work, a point-matching meshless...
The reconstruction of dielectric objects is performed by the contrast source inversion method (CSIM) under a limited observation. The CSIM is superior to the traditional Born iterative method (BIM) or its variations because it updates the contrast source and contrast simultaneously and avoids the direct solution of forward scattering integral equation (FSIE). The CSIM is similar to the modified gradient...
Accurate solution of electromagnetic (EM) problems with complex materials requires the formulation of volume integral equations (VIEs) in the integral equation approach. The VIEs are traditionally solved by the method of moments (MoM) with the Schaubert-Wilton-Glisson (SWG) basis function, but we propose a point-matching scheme which does not relies on any basis and testing functions and allows the...
Solving volume integral equations (VIEs) with anisotropic media usually relies on the method of moments (MoM) with the divergence-conforming Schaubert-Wilton-Glisson (SWG) basis function or curl-conforming edge basis function. However, the basis functions may not be suitable to represent unknown functions when the anisotropy of media is strong. In this work, we replace the MoM with a point-matching...
The shunt reactors are important components in the EHV/UHV (Eltra/Ultra High Voltage) power systems used for the voltage regulation issues. One of their important roles is to compensate the reactive power. Typically for such compensation the fixed shunt reactors are used. Alternative concepts introduced recently are the controllable reactors. The controlling effect of orthogonal flux type controllable...
