Broadband quasistatic passive cloaking: bounds and limitations in the near-field regime

Maxence Cassier, Graeme W. Milton, Aaron Welters

We consider here several aspects of the following challenging question: is it possible to use a passive cloak to make invisible a dielectric inclusion on a finite frequency interva…

Geometric spectral properties of electromagnetic waveguides

Philippe Briet, Maxence Cassier, Thomas Ourmières-Bonafos +1

Consider a reference homogeneous and isotropic electromagnetic waveguide with a simply connected cross-section embedded in a perfect conductor. In this setting, when the waveguide…

An operator approach to the analysis of electromagnetic wave propagation in dispersive media. Part 1: general results

Maxence Cassier, Patrick Joly

We investigate in this chapter the mathematical models for electromagnetic wave propagation in dispersive isotropic passive linear media for which the dielectric permittivity $\var…

An operator approach to the analysis of electromagnetic wave propagation in dispersive media. Part 2: transmission problems

Maxence Cassier, Patrick Joly

In this second chapter, we analyse transmission problems between a dielectric and a dispersive negative material. In the first part, we consider a transmission problem between two…

Long time behaviour of the solution of Maxwell's equations in dissipative generalized Lorentz materials (II) A modal approach

Maxence Cassier, Patrick Joly, Luis Alejandro Rosas Martínez

This work concerns the analysis of electromagnetic dispersive media modelled by generalized Lorentz models. More precisely, this paper is the second of two articles dedicated to th…
