High-order quasi-curl conforming functions for multiplicative Calderón preconditioning of the EFIE
2009 Edition, June 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Method of moments (MoM)-based electric field integral equation (EFIE) solvers are widely used for analyzing time-harmonic electromagnetic scattering from perfect electrically conducting (PEC) surfaces. In the last decade, MoM-based EFIE solvers using...

Fully localized high-order div- and quasi-curl-conforming basis functions for multiplicative Calderón preconditioning of the EFIE
2010 Edition, July 1, 2010 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Method of moments (MoM)-based electric field integral equation (EFIE) solvers are widely used for analyzing time-harmonic electromagnetic scattering from perfect electrically conducting (PEC) surfaces [1]. That said, MoM-EFIE solvers are no panacea. Indeed, the...

High-order Div- and Quasi Curl-Conforming Basis Functions for Calderón Multiplicative Preconditioning of the EFIE
2011 Edition, Volume 59, April 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

A new high-order Calderón multiplicative preconditioner (HO-CMP) for the electric field integral equation (EFIE) is presented. In contrast to previous CMPs, the proposed preconditioner allows for high-order surface...

Implementation of the Calderón multiplicative preconditioner for the efie solution with curvilinear triangular patches
2009 Edition, June 1, 2009 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The electric field integral equation (EFIE) has been widely used in the moment method (MoM) solution of electromagnetic problems. However, due to the spectrum property of the EFIE operator, the resulting MoM impedance matrix has...

2017 Edition, July 1, 2017 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We present a new formulation for the Impedance Boundary Condition - Electric Field Integral Equation (IBC-EFIE) which requires a number of iterations to be solved that is bounded at low frequency and with dense meshes. We use a multiplicative...

A well conditioned EFIE for capacitance extraction
2016 Edition, June 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The most common use of the EFIE is the computation of radar cross sections for globally electrically neutral scatterers. In this case the current density on the scatterer is approximated in RWG functions and thus, by...

A novel preconditioner for the EFIE discretised with the H div inner product
2017 Edition, March 1, 2017 - ACES

A novel preconditioning for the electric field integral equation (EFIE) discretised with the Hdiv inner product is discussed. It is known that the EFIE suffers from bad accuracy in low-frequency problems. One of the remedies for...

A Multiplicative Calderon Preconditioner for the Electric Field Integral Equation
2008 Edition, Volume 56, August 1, 2008 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

In this paper, a new technique for preconditioning electric field integral equations (EFIEs) by leveraging Calderon identities is presented. In contrast to all previous Calderon preconditioners, the proposed preconditioner is purely...
