Negative radiation pressure and negative effective refractive index via dielectric birefringence.
We show that light guided in a planar dielectric slab geometry incorporating a biaxial medium has lossless modes with group and phase velocities in opposite directions. Particles in a vacuum gap inserted into the structure experience negative radiation pressure: the particles are pulled by light rather than pushed by it. This effectively one-dimensional dielectric structure represents a new geo...

متن کاملNegative Refractive Index in Optics of Metal-Dielectric Composites
Specially designed metal-dielectric composites can have a negative refractive index in the optical range. Specifically, it is shown that arrays of single and paired nanorods can provide such negative refraction. For pairs of metal rods, a negative refractive index has been observed at 1.5 μm. The inverted structure of paired voids in metal films may also exhibit a negative refractive index. A s...
متن کاملReflection from a Flat Dielectric Film with Negative Refractive Index
We analyse the reflection of a TM electromagnetic field first on a flat dielectric film and second on a Veselago film with negative refractive index, both films being deposited on a metallic substrat acting as a mirror. An incident harmonic plane wave generates inside a conventional dielectric film a refracted propagating wave and an evanescent wave that does not contribute to reflection on the...
متن کاملIdentity Synthesis: Creating An Identity From Scratch
A substantial quantity of research has previously been conducted into the identification and application of measures related to the detection and prevention of identity theft and identity fraud. In the current security conscious environment, the concept of creating an artificial identity is generally met with both caution and suspicion. Much of the attention placed on the concept of identity fa...
