Far field broadband approximate cloaking for the Helmholtz equation with a Drude-Lorentz refractive index

Fioralba Cakoni, Narek Hovsepyan, Michael Vogelius

This paper concerns the analysis of a passive, broadband approximate cloaking scheme for the Helmholtz equation in ${\mathbb{R}}^d$ for $d=2$ or $d=3$. Using ideas from transformati…
