During the past few years, metasurfaces have been used to demonstrate optical elements
and systems with capabilities that surpass those of conventional diffractive optics. Here, we …

This paper is a critical review of metasurfaces, which are planar metamaterials.
Metamaterials offer bespoke electromagnetic applications and novel properties which are …

Relying on abrupt phase discontinuities, metasurfaces characterized by a transversely
inhomogeneous surface impedance profile have been recently explored as an ultrathin …

The use of the generalized Snell's law opens wide possibilities for the manipulation of
transmitted and reflected wavefronts. However, known structures designed to shape …

Nonuniform metasurfaces (electrically thin composite layers) can be used for shaping
refracted and reflected electromagnetic waves. However, known design approaches based …

We present a computational framework for efficient optimization-based “inverse design” of
large-area “metasurfaces”(subwavelength-patterned surfaces) for applications such as multi …

We review the current trends in the design of Huygens' metasurfaces (HMSs), which are
planar arrays of balanced electric and magnetic polarizable particles (meta-atoms) of …
