Metamaterials are composed of periodic subwavelength metal/dielectric structures that
resonantly couple to the electric and/or magnetic components of the incident …

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 …

Metasurfaces are ushering in an era of multifunctional control over optical wavefronts
realized with ultrathin planarized devices. Recent advances have been enabling …

This tutorial provides an intuitive and concrete description of the phenomena of
electromagnetic nonreciprocity that will be useful for readers with engineering or physics …

Polarization is one of the basic properties of electromagnetic waves conveying valuable
information in signal transmission and sensitive measurements. Conventional methods for …

Janus monolayers, a class of two‐faced 2D materials, have received significant attention in
electronics, due to their unusual conduction properties stemming from their inherent out‐of …

Methods to analyze and synthesize two-dimensional, bianisotropic metamaterials
(metasurfaces) are presented. First, a general bianisotropic metasurface is analyzed by …

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 …

It is experimentally shown that bianisotropic metasurfaces allow for extreme polarization
control of light with high performance. A metasurface providing asymmetric transmission (ie …

Achieving simultaneous polarization and wavefront control, especially circular polarization
with the auxiliary degree of freedom of light and spin angular momentum, is of fundamental …
