Negative refraction without negative index in metallic photonic crystals.
نویسندگان
چکیده
It is shown that certain metallic photonic crystals can enable negative refraction and subwavelength imaging without relying on a negative effective index. These metallic structures are very simple in design and appear straightforward for fabrication. Their unusual electromagnetic response should provide an interesting comparison with the metallic left-handed materials.

A Systematic Approach to Photonic Crystal Based Metamaterial Design
Photonic crystal design procedure for negative refraction has so far been based on trial and error. In this paper, for the first time, a novel and systematic design procedure based on physical and mathematical properties of photonic crystals is proposed to design crystal equi-frequency contours (EFCs) to produce negative refraction. The EFC design is performed by the help of rectangular stair-c...
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 کاملNegative refraction and left-handed behavior in two-dimensional photonic crystals
We systematically examine the conditions of obtaining left-handed ~LH! behavior in photonic crystals. Detailed studies of the phase and group velocities as well as the phase np and group ng refractive indices are given. The existence of negative refraction does not guarantee the existence of negative index of refraction and so LH behavior. A wedge type of experiment is suggested, which can unam...
متن کاملAll-angle negative refraction without negative effective index
Negative refraction of electromagnetic waves in ‘‘lefthanded materials’’ has become of interest recently because it is the foundation for a variety of novel phenomena. In particular, it has been suggested that negative refraction leads to a superlensing effect that can potentially overcome the diffraction limit inherent in conventional lenses. These phenomena have been described in the context ...
متن کاملNegative refraction and focusing of electromagnetic waves by metallodielectric photonic crystals
In this work, we have experimentally and theoretically studied negative refraction of electromagnetic waves by a metallodielectric photonic crystal. We showed that by adding a periodic dielectric perturbation to the unit cell of a metallic photonic crystal, it is possible to increase the range of incidence angles at which the electromagnetic waves are negatively refracted. We obtained negative ...
