A CalderÓn Multiplicative Preconditioner for the Combined Field Integral Equation
IEEE Transactions on Antennas and Propagation, 2009A Calderon multiplicative preconditioner (CMP) for the combined field integral equation (CFIE) is developed. Just like with previously proposed Calderon-preconditioned CFIEs, a localization procedure is employed to ensure that the equation is resonance ...

A Novel Wideband FMM for Fast Integral Equation Solution of Multiscale Problems in Electromagnetics
IEEE Transactions on Antennas and Propagation, 2009In this paper, we propose a novel scheme to accelerate integral equation solvers when applied to multiscale problems. These class of problems exhibit multiple length/frequency scales and arise when analyzing scattering/radiation from realistic structures

A multiplicative Calderón preconditioner for the electric field integral equation
IEEE Antennas and Propagation Society International Symposium, 2008A new technique for preconditioning electric field integral equations (EFIEs) by leveraging Calderon identities is presented. In contrast to all previous Calderon EFIE preconditioners, the proposed preconditioner is purely multiplicative in nature ...

A novel formulation of the volume integral equation for electromagnetic scattering
, 2009A novel method to solve the volume integral equation involving inhomogeneous and anisotropic permittivity and permeability dielectric objects is introduced. A curl-conforming edge element is used to model the electric field distributions. This simplifies

An augmented electric field integral equation for high‐speed interconnect analysis
, 2008The conventional electric field integral equation (EFIE) is augmented by including charge as the extra unknown, so that the contributions of the vector potential and the scalar potential are separated to avoid the imbalance at low frequencies.
