Weaving one-way threads into non reciprocal meta-surfaces: The meta-weaves

Abstract

Confluent with the single dimension of time, breach of time-reversal symmetry is usually perceived as a one-dimensional concept. However, strongly non-reciprocal or oneway nano-scale threads can be used to weave meta-surfaces thus systematically adding dimensions to this concept. The resulting surfaces-the meta-weaves-posses generalized non-reciprocity such as “sector-way” propagation, and offer new possibilities for controlling light in thin surfaces. We provide several meta-weave designs and study their properties.
