This article reviews recent progress leading to the realization of planar optical components
made of a single layer of phase shifting nanostructures. After introducing the principles of …

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 …

Traditionally,“metamaterials” have been described by effective medium parameters due to
the subwavelength nature of unit particles. The continuous nature of medium parameters …

Metamaterials are typically engineered by arranging a set of small scatterers or apertures in
a regular array throughout a region of space, thus obtaining some desirable bulk …

This article covers recent advances in the fusion of metasurface antenna design and
computational imaging (CI) concepts for the realization of imaging systems that are planar …

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

Over the past 5 years, digital coding and programmable metamaterials have been
developed rapidly since their first exhibition in 2014. The iconic feature of the digital coding …

A metasurface (MS) used to convert the linearly polarized (LP) signal from a source antenna
into a circularly polarized (CP) signal is proposed and studied. The MS consists of 16 unit …

The impedance matching to free space in metamaterial perfect absorbers has been believed
to involve and rely on magnetic resonant response, with direct evidence provided by the anti …

A general method, based on susceptibility tensors, is proposed for the synthesis of
metasurfaces transforming arbitrary incident waves into arbitrary reflected and transmitted …
