Artificial chiral nanostructures have been subjected to extensive research for their unique
chiroptical activities. Planarized chiral films of ultrathin thicknesses are in particular demand …

The scientific effort to control the interaction between light and matter has grown
exponentially in the last 2 decades. This growth has been aided by the development 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 …

The ideal material for nanophotonic applications will have a large refractive index at optical
frequencies, respond to both the electric and magnetic fields of light, support large optical …

Recently, developments in meta-surfaces have allowed for the possibility of a fundamental
shift in lens manufacturing from the century-old grinding technology to nanofabrication …

Self-oscillation can harvest energy directly from the environment to maintain its motion and
is characterized by its autonomy, with various promising applications in the fields of …

Chirality or handedness distinguishes an object from its mirror images, such as the spread
thumb, index finger, and middle finger of the right and left hand. In mathematics, it is …

Throughout the 19th and 20th century, chirality has mostly been associated with chemistry.
However, while chirality can be very useful for understanding molecules, molecules are not …

The strong optical chirality arising from certain synthetic metamaterials has important and
widespread applications in polarization optics, stereochemistry and spintronics. However …

Optical communications, laser science, microscopy and metrology demand control of light
polarization, which is also used as a probe of chemical and biological systems. Typically …
