Scattering Forces within a Left-Handed Photonic Crystal
Electromagnetic waves are known to exert optical forces on particles through radiation pressure. It was hypothesized previously that electromagnetic waves inside left-handed metamaterials produce negative radiation pressure. Here we numerically examine optical forces inside left-handed photonic crystals demonstrating negative refraction and reversed phase propagation. We demonstrate that even t...
متن کاملPhotonic Approach to Making a Left-Handed Material
A new approach to producing a composite material with negative refraction index is demonstrated. It is shown that a photonic structure which consists of two dielectric materials, with positive and negative dielectric permittivities, can support electromagnetic waves which exhibit the unusual electromagnetic property of left-handedness (or negative refraction index). These electromagnetic waves ...
متن کاملNegative refraction and left-handed electromagnetism in microwave photonic crystals.
We demonstrate the negative refraction of microwaves in a metallic photonic crystal prism. The spectral response of the photonic crystal prism, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical simulations. The validity of Snell's law with a negative refractive index is confirmed experimentally and theoretically. The n...
متن کاملAnalytical Investigation of TM Surface Waves in 1D Photonic Crystals Capped by a Self-Focusing Left-Handed Slab
In this paper, the localized TM surface waves of a nonlinear self-focusingleft-handed slab sandwiched between a uniform medium and a one-dimensionalphotonic crystal (1D PC) is analytically investigated. Our method is based on the firstintegral of the nonlinear Maxwell's equations. For the TM surface waves, the presenceof two electric field components makes the analysis difficult. Therefore, we ...
متن کاملGiant Goos-Häenchen Shift of a Gaussian Beam Reflected from One-Dimensional Photonic Crystals Containing Left-Handed Lossy Metamaterials
We perform a theoretical investigation on the Goos-Häenchen shift (the lateral shift) in one-dimensional photonic crystals (1DPCs) containing left-handed (LH) metamaterials. The effect was studied by use of a Gaussian beam. We show that the giant lateral displacement is due to the localization of the electromagnetic wave which can be both positive and negative depending on the incidence angle o...
