Surface plasmons (SPs) are electromagnetic surface waves that propagate at the interface
between a conductor and a dielectric. Due to their unique ability to concentrate light on two …

Background Metamaterials (MMs) are smartly engineered structures with rationally
designed, nanostructured building blocks that allow us to build devices with distinct …

We combine theory and experiment to demonstrate that a carefully designed gradient meta-
surface supports high-efficiency anomalous reflections for near-infrared light following the …

The arbitrary control of electromagnetic waves is a key aim of photonic research. Although,
for example, the control of freely propagating waves (PWs; refs,,,,,) and surface waves (SWs; …

Metamaterials, artificial composite structures with exotic material properties, have emerged
as a new frontier of science involving physics, material science, engineering and chemistry …

Digital phase shifters have been applied in traditional phased array antennas to realize
beam steering. However, the phase shifter deals with the phase of the induced current; …

Control over light absorption and emission using plasmonic nanostructures is an enabling
technology, which can dramatically enhance the performances of existing optical and …

The field of transformation optics shows that media containing gradients in optical properties
are equivalent to curved geometries of spacetime for the propagation of light. Conformal …

Our intuitive understanding of light has its foundation in the ray approximation and is
intimately connected with our vision. As far as our eyes are concerned, light behaves like a …

We demonstrate experimentally the generation and near-field imaging of nondiffracting
surface waves, plasmonic Airy beams, propagating on the surface of a gold metal film. The …
