Abstract: A new Surface–Volume–Surface Electric Field Integral Equation (SVS-EFIE) is discussed. The SVS-EFIE is derived from the volume integral equation by representing the electric field inside the scatterer as a superposition of the waves emanating from its cross section’s boundary. The SVS-EFIE has several advantages. While being rigorous in nature, it features half of the degrees of freedom compared to the traditional surface integral equation formulations such as PMCHWT and it requires only electric-field-type of Green’s function instead ofboth electric and magnetic field types. The latter property brings significant simplifications to solution of the scattering problems on the objects situated in multilayered media.
Both scalar and vector formulations of the SVS-EFIE equation has been developed for solution of 2D scattering problems on penetrable cylinders under TM and TE polarizations. The SVS-EFIE has been also been applied to the solution of the quasi-magneetostatic problems of current flow in complex interconnects in both homogeneous and multilayered media. Detailed description of the method of moment discretization and resultant matrices is discussed. Due to the presence of a product of surface-to-volume and volume-to-surface integral operators, the discretization of the novel SVS-EFIE requires both surface and volume meshes. In order to validate the presented technique, the numericalresults are compared with the reference solutions.
Biography: Vladimir Okhmatovski received Ph.D. degree in antennas and microwave circuits from the Moscow Power Engineering Institute, Moscow, Russia in 1997. He was a Post-Doctoral Research Associate with the National Technical University of Athens from 1998 to 1999 and with the University of Illinois at Urbana-Champaign from 1999 to 2003. From 2003 to 2004, he was with the Department of Custom Integrated Circuits at Cadence Design Systems in Tempe, Arizona. In 2004, he joined the Department of Electrical and Computer Engineering, University of Manitoba, where is currently an Associate Professor. His research interests are the fast algorithms of electromagnetics, high-performance computing, modeling of interconnects, and inverse problems.
