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 …

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 present detailed analytical modeling and in-depth investigation of wide-angle reflect-
mode metagrating beam splitters. These recently introduced ultrathin devices are capable of …

This paper presents a simple and effective way to increase the scan range of phased array
antennas by using a metasurface (MTS) curved dome. The technique is based on a phase …

Huygens' metasurfaces, typically designed using sub-wavelength unit cells, allow the
arbitrary control of electromagnetic waves. Two well-known unit-cell topologies are the wire …

In this paper, we applied the circuit synthesis theory of filters to the design of transmission-
type metasurface cells and arbitrarily designed the amplitude and phase of the transmission …

As applications involving electromagnetic waves as carriers of energy and information have
become common in society, the ability to tailor and control electromagnetic fields has …

In this article, a new transmission-line-based analysis is introduced to design the gradient
and Huygens' metasurfaces. In this method, each unit cell of the gradient and Huygens' …

Refraction represents one of the most fundamental operations that may be performed by a
metasurface. However, simple phasegradient metasurface designs suffer from restricted …
