Metasurfaces as optically thin composite layers can be modeled as electric and magnetic
surface current sheets flowing in the layer volume in the metasurface plane. In the most …

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 …

Metasurfaces have provided unprecedented freedom for manipulating electromagnetic
waves. In metasurface design, massive meta-atoms have to be optimized to produce the …

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 …

Recent advances in gradient metasurfaces have shown that by locally controlling the
bianisotropic response of the cells one can ensure full control of refraction, that is, arbitrarily …

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

Metasurfaces consisting of electrically thin and densely packed planar arrays of
subwavelength elements enable an unprecedented control of the impinging electromagnetic …

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 …
