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 …

In this article, the basic principles and the main applications of Huygens' metasurfaces
(HMSs) are reviewed from microwaves to optics. In general, HMSs comprise a thin layer of …

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

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

In this paper, we propose a new metasurface that is able to reflect a known incoming
electromagnetic wave into an arbitrary direction, with perfect power efficiency. This …

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 …

We introduce a paradigm for accurate design of metasurfaces for intricate beam
manipulation, implementing functionalities previously considered impossible to achieve with …

We present a general theory for designing realistic omega-type bianisotropic metasurfaces
(O-BMSs), unlocking their full potential for molding electromagnetic fields. These …

Pancharatnam-Berry (PB) metasurfaces exhibit strong abilities to control spin-polarized light,
but transmission-mode PB functional devices exhibiting simultaneously nearly 100 …
