Slow light, open cavity formation, and large longitudinal electric field on slab waveguide made of indefinite permittivity materials
W. T. Lu, S. Sridhar
The optical properties of slab waveguides made of indefinite permittivity ($\vep$) materials (IEM) are considered. In this medium the transverse permittivity is negative while the…
Superlens imaging theory for anisotropic nanostructured metamaterials with broadband all-angle negative refraction
W. T. Lu, S. Sridhar
We show that a metamaterial consisting of aligned metallic nanowires in a dielectric matrix has strongly anisotropic optical properties. For filling ratio f<1/2, the composite medi…
Alternative approach to all-angle negative refraction in two-dimensional photonic crystals
Y. J. Huang, W. T. Lu, S. Sridhar
We show that with an appropriate surface modification, a slab of photonic crystal can be made to allow wave transmission within the band gap. Furthermore, negative refraction and a…
From chaos to disorder: Statistics of the eigenfunctions of microwave cavities
Prabhakar Pradhan, S. Sridhar
We study the statistics of the experimental eigenfunctions of chaotic and disordered microwave billiards in terms of the moments of their spatial distributions, such as the Inverse…
Quantum correlations and classical resonances in an open chaotic system
Wentao T. Lu, Kristi Pance, Prabhakar Pradhan +1
We show that the autocorrelation of quantum spectra of an open chaotic system is well described by the classical Ruelle-Pollicott resonances of the associated chaotic strange repel…
Quantum fingerprints of classical Ruelle-Pollicot resonances
Kristi Pance, Wentao Lu, S. Sridhar
N-disk microwave billiards, which are representative of open quantum systems, are studied experimentally. The transmission spectrum yields the quantum resonances which are consiste…
