We propose a III–V semiconductor photonic crystal slab designed to operate as a n = −1 superlens at λ 0 = 1.55 μm. The structure consists of air holes arranged in a two-dimensional triangular lattice, of period a, nanopatterned in an InP/InGaAs

We present experimental results as well as modelling concerning terahertz (THz) wave scattering by powder materials with grain size of the order of the wavelength. The studied material is a mixture of high density polyethylene and fructose powders, w

2013 38th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz).
In security applications, items or substances of interest are generally hidden and therefore, for body inspection, must be identified through clothes. We show that diffractive behavior of fabrics when illuminated by THz wave can complicate such appro

The structure of most of fabrics is an almost periodic network of interlaced yarns or threads, whose periodicity is of the order of the terahertz wavelength. We report here on the diffraction of terahertz electromagnetic waves by the yarn network in

An n=-1 flat lens based on photonic crystal semiconductor technology is evaluated for infrared detection purposes. The idea consists in exploiting the backscattered waves of an incident plane wave impinging on a target placed in the focal region of a

In this paper, we present photonic crystal flat lenses with interfaces engineered to improve the light transmittance thanks to a broad angles impedance matching. The interface engineering consists in the realization of antireflection gratings on the
