Abstract

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.
