Efficient analysis of 2D cloaking with 3D devices and of related bandwidth limitation

Primary tabs

Craeye, Christophe [UCL] Batthacharya, A. Gonzalez Ovejero, David

2D structures made of 3D metamaterial inclusions often exhibit a sectoral symmetry. This enables a vastly accelerated Method-of-Moment analysis of such structures. Further acceleration is offered by the multipole decomposition of the linear infinite-array Green's function. Such methods allow the fast frequency-domain response of cloaking metamaterials and in particular of their maximum bandwidth, which is shrinking for larger objects in terms of wavelengths, due to causality limitations.
