Broadband Stable Calderón-Preconditioned Vector-Potential-Only Integral Equations for PEC Scattering
Paul Olyslager, Hendrik Rogier, Kristof Cools
We propose a stabilized first-kind, Calderón preconditioned, vector-potential-only integral equation, for scattering at perfect electrical conductors. The method yields accurate lo…
Suppressing Low-Frequency Cancellation Errors in Far-Field Computation with the MFIE, Müller, and Multitrace Müller Integral Equations
Chien V. Le, Kristof Cools
This paper presents robust numerical formulations for suppressing low-frequency cancellation errors in the magnetic field integral equation (MFIE) for perfect electric conductors a…
Multitrace Müller Boundary Integral Equation for Electromagnetic Scattering by Composite Objects
Van Chien Le, Kristof Cools
This paper introduces a boundary integral equation for time-harmonic electromagnetic scattering by composite dielectric objects. The formulation extends the classical Müller equati…
Boundary element methods for the magnetic field integral equation on polyhedra
Van Chien Le, Kristof Cools
This paper provides a rigorous analysis of boundary element methods for the magnetic field integral equation on Lipschitz polyhedra. The magnetic field integral equation is widely…
