High-order quasi-Helmholtz Projectors: Definition, Analyses, Algorithms
Johann Bourhis, Adrien Merlini, Francesco P. Andriulli
The accuracy of the electric field integral equation (EFIE) can be substantially improved using high-order discretizations. However, this equation suffers from ill-conditioning and…
