TL;DR: This work identifies a novel higher-order magnetic resonance at around 370 THz (800 nm wavelength) that evolves out of the Mie resonance for oblique incidence and shows that the structures allow for a negative magnetic permeability.

TL;DR: The finite element method is applied to the optimization of the design of a hollow core photonic crystal fiber and the convergence of the method is looked at to discuss automatic and adaptive grid refinement and the performance of higher order elements.

TL;DR: In this paper, the authors apply the adaptive finite element method to the optimization of the design of a hollow core photonic crystal fiber and discuss automatic and adaptive grid refinement and the performance of higher order elements.

TL;DR: It is proved that the approximate solution obtained by the PML method converges exponentially fast to the true solution in the computational domain as the thickness of the sponge layer tends to infinity.

TL;DR: This work benchmarks several methods for implementing efficient and accurate QNM solvers for computing and normalizing the QNMs of micro- and nanoresonators made of highly dispersive materials, and compares them to elaborate standards for the computation of resonance modes.
