We review the recently emerged class of hybrid metal‐dielectric colloidal photonic crystals.
The hybrid approach is understood as the combination of a dielectric photonic crystal with a …

The visionary work of Veselago had inspired intensive research efforts over the last decade,
towards the realization of man-made structures with unprecedented electromagnetic (EM) …

Inspired by the concept of complementary media, we experimentally demonstrate that an
engineered metamaterial made of alternating, stripe layers of negatively refracting (photonic …

Based on the triangular lattice two-dimensional photonic crystal (PC), the lattice spacing
along the transverse direction to propagation is altered, and a gradient PC (GPC) flat lens is …

We introduce a class of optical media based on adiabatically modulated, dielectric-only, and
potentially extremely low-loss, photonic crystals (PC). The media we describe represent a …

A hybrid metal-dielectric photonic crystal, a thin opal slab coated by a gold film, has been
designed in order to exercise additional control upon the light propagation in a photonic …

A comprehensive analysis of the coupling coefficients between plane waves in conventional
dielectric media and Bloch waves of photonic crystals with effective negative refractions is …

Reflection and transmission spectra of two-dimensional photonic crystal slabs, fabricated by
photoelectrochemical etching of deep macropores and trenches in Si, are investigated …

A dielectric structure with effective permittivity and permeability close to− 1 operating for
propagative waves at optical wavelengths is proposed. This structure is a two-dimensional …

We demonstrate the numerical design and the experimental validation of frequency
dependent directional emission from a dielectric photonic crystal structure. The wave …
