Phononic crystals have been proposed about two decades ago and some important
characteristics such as acoustic band structure and negative refraction have stimulated …

Mechanical metamaterials, also known as architected materials, are rationally designed
composites, aiming at elastic behaviors and effective mechanical properties beyond ('meta') …

Since the advent of quantum mechanics and the clear demonstration of the existence
of'matter waves', physicists have never failed to take advantage of concepts and theoretical …

The large amount of light emitted from a light emitting diode (LED) being trapped inside the
semiconductor structure is the consequence of the large value of the refractive index. The …

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 …

Refraction is a basic beam bending effect at two media's interface. While traditional studies
focus on stationary boundaries, moving boundaries or potentials could enable new laws of …

This work presents the design and fabrication of a metamaterial-based stimulated dual band
antenna on FR4 material (dielectric constant 4.3) to operate in Industrial, Scientific and …

We show that optical beams propagating in path-averaged zero-index photonic crystal
superlattices can have zero phase delay. The nanofabricated superlattices consist of …

The quantum interference between two spontaneous emission transitions, which are
orthogonal, in a three-level system, can be greatly enhanced by using left-handed materials …

The study explores the Fano-type interference effect in a microstrip photonic crystal (PC)
heterostructure integrated with a varactor-loaded split ring resonator (SRR), both …
