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 …

We review the basic physics and applications of a special class of planar metamaterials,
often called metasurfaces, which are composed of optically thin and densely packed planar …

A revolutionary technology relying on Stacked Intelligent Metasurfaces (SIM) is capable of
carrying out advanced signal processing directly in the native electromagnetic (EM) wave …

In the wake of intense research on metamaterials the two-dimensional analogue, known as
metasurfaces, has attracted progressively increasing attention in recent years due to the …

Metasurfaces are planar structures that locally modify the polarization, phase and amplitude
of light in reflection or transmission, thus enabling lithographically patterned flat optical …

The emerging metasurfaces with the exceptional capability of manipulating an arbitrary
wavefront have revived the holography with unprecedented prospects. However, most of the …

The angular response of thin diffractive optical elements is highly correlated. For example,
the angles of incidence and diffraction of a grating are locked through the grating momentum …

Metasurfaces are a topic of significant research and are used in various applications due to
their unique ability to manipulate electromagnetic waves in microwave and optical …

Regarding miniaturized and integrated systems, a single flat device that possesses
diversified functionalities is highly desirable in optical to microwave regimes. With this …
