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 …

The paper briefly presents some essential concepts and features of light fields with strong
spatial inhomogeneity of amplitude, phase, polarization, and other parameters. It contains a …

Maxwell's equations, formulated 150 years ago, ultimately describe properties of light, from
classical electromagnetism to quantum and relativistic aspects. The latter ones result in …

This Colloquium presents an overview of the research on nonlinear electromagnetic
metamaterials. The developed theoretical approaches and experimental designs are …

Soliton resonances and soliton molecules play a vital role to generate stable high-energy
waves in nonlinear system. Meanwhile, higher-order dispersions and higher-order …

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 …

Maxwell electromagnetism, describing the wave properties of light, was formulated 150
years ago. More than 60 years ago it was shown that interfaces between optical media …

Ever since the first experimental demonstration was reported in 2000, the interest in
metamaterials and left-handed media that exhibit a negative refractive index has increased …

We develop an approach to build a material with negative refraction index that can be
implemented for optical and infrared frequencies. In contrast to conventional designs that …

We study experimentally the dynamic tunability and self-induced nonlinearity of split-ring
resonators incorporating variable capacitance diodes. We demonstrate that the …
