The powerful tools of transformation optics (TO) allow an effective distortion of a region of
space by carefully engineering the material inhomogeneity and anisotropy, and have been
successfully applied in recent years ...

We show that it is possible to realize a passive planar
reflector whose reflectivity (close to the resonant frequency of
the reflector structure) is larger than unity. This reflector is
strongly coupled to evanescent ...

Recently, it was shown that by using special artificial materials it is possible to ensure that all electromagnetic
modes of free space are conjugately matched to the modes of a material body and, thus, all modes deliver ...

The topics here deal with some current progress in electromagnetic wave propagation in a family of substances known as metamaterials. To begin with, it is discussed how a pulse can develop a leading edge that steepens and ...
Gangaraj, S Ali Hassani; Monticone, Francesco; Valagiannopoulos, Constantinos(Nanomaterials and Nanotechnology, 2018-09)
Anomalous scattering effects (invisibility, superscattering, Fano resonances, etc) enabled by complex media and metamaterials
have been the subject of intense efforts in the past couple of decades. In this article, we ...
