Dispersive Perfectly Matched Layer and high order Absorbing Boundary Conditions for the computation of Quasinormal modes of open electromagnetic structures
Guillaume Demésy, Tong Wu, Yoann Brûlé +4
Resonances, also known as quasinormal modes (QNM) in the non-Hermitian case, play a ubiquitous role in all domains of physics ruled by wave phenomena, notably in continuum mechanic…

Electrodynamics of an oscillating particle without cheating PART I : In vacuo. PART II : Near a dispersive bulk
Mauricio Garcia-Vergara, Guillaume Demésy, André Nicolet +1
In this paper, the electromagnetic radiation from an oscillating particle placed in the vicinity of an object of size comparable to the wavelength is studied. Although this problem…
