Abstract

Chiral effects and optical activity have been a central topic of
interest in optics and artificial materials for several decades. Here
we discuss and model the physical mechanisms behind extrinsic
chiral effects induced over ultrathin plasmonic metasurfaces and
in optical metamaterials characterized by controlled arrangements
of stacked metasurfaces. We explain these effects using analytical
models, supported and validated by full-wave simulations. In this
chapter, we provide physical insights into the anomalous optical
effects offered by these nanodevices and we envision potential
optical applications of these concepts.
