Resonances in Axially Symmetric Dielectric Objects

Helsing, Johan LU and Karlsson, Anders LU (2017) In IEEE Transactions on Microwave Theory and Techniques 65(7). p.2214-2227
Abstract

A high-order convergent and robust numerical solver is constructed and used to find complex eigenwavenumbers and electromagnetic eigenfields of dielectric objects with axial symmetry. The solver is based on Fourier-Nyström discretization of combined integral equations for the transmission problem and can be applied to demanding resonance problems at microwave, terahertz, and optical wavelengths. High achievable accuracy, even at very high wavenumbers, makes the solver ideal for benchmarking and for assessing the performance of general-purpose commercial software.
