Analytic preconditioners for decoupled potential integral equations and wideband analysis of scattering from PEC objects
J. A. Hawkins, L. Baumann, H. M. Aktulga +2
Many integral equations used to analyze scattering, such as the standard combined field integral equation (CFIE), are not well-conditioned for a wide range of frequencies and multi…
An Envelope Tracking Approach for Particle in Cell Simulations
Omkar H. Ramachandran, Zane D. Crawford, Scott O'Connor +2
The state of the art in electromagnetic Finite Element Particle-in-Cell (EM-FEMPIC) has advanced significantly in the last few years. These have included understanding function spa…
Transient dynamics of subradiance and superradiance in open optical ensembles
Elliot Lu, B. Shanker, Carlo Piermarocchi
We introduce a computational Maxwell-Bloch framework for investigating out-of-equilibrium optical emitters in open systems. To do so, we compute the pulse-induced dynamics of each…
A Complete Helmholtz Decomposition on Multiply Connected Subdivision Surfaces and Its Application to Integral Equations
A. M. A. Alsnayyan, L. Kempel, B. Shanker
The analysis of electromagnetic scattering in the isogeometric analysis (IGA) framework based on Loop subdivision has long been restricted to simply-connected geometries. The inabi…
