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 …

We review basic physics and novel types of optical angular momentum. We start with a
theoretical overview of momentum and angular momentum properties of generic optical …

Despite the extraordinary degree of interest in optical metamaterials in recent years, the
hoped-for devices and applications have, in large part, yet to emerge. It is becoming clear …

Optical chiral metamaterials have recently attracted considerable attention because they
offer new and exciting opportunities for fundamental research and practical applications …

Circularly polarized light (CPL) exhibits an enantioselective interaction with chiral
molecules, providing a pathway toward all-optical chiral resolution. High index dielectric …

One of the most intuitive ways to classically understand the generation of natural optical
activity in chiral media is provided by the coupled oscillator model of Born and Kuhn …

The dual symmetry between electric and magnetic fields is an important intrinsic property of
Maxwell equations in free space. This symmetry underlies the conservation of optical helicity …

Chiral-optical spectroscopies, such as circular dichroism, are critical in the biomedical,
pharmaceutical, and agrochemical industries for revealing structural information about …

We consider ap-polarized surface electromagnetic wave (a classical surface polariton) at the
interface between the vacuum and a metal or left-handed medium. We show that the …

Chirality plays an essential role in life, providing unique functionalities to a wide range of
biomolecules, chemicals, and drugs, which makes chiral sensing and analysis critically …
