Partially coherent sources which produce the same far zone optical force as a laser beam
Juan Miguel Auñon, Manuel Nieto-Vesperinas
On applying a theorem previously derived by Wolf and Collett, we demonstrate that partially coherent Gaussian Schell model uctuating sources (GSMS) produce exactly the same optical…
Comments on: "Universal Features of Time Dynamics in a Left-Handed Perfect Lens" by G.Gomez-Santos
N. Garcia, M. Nieto-Vesperinas
Recently, we have shown the impossibility of perfect lensing with left-handed material slabs, gue to the divergence of the wavefield norm, and hence to the infinite enegy that woul…
Theory for tailoring sonic devices: Diffraction dominates over Refraction
N. Garcia, M. Nieto-Vesperinas, E. V. Ponizovskaya +1
In the moderately long wavelength propagation regime, acoustic crystaldevices which size is of several wave lengths are studied by using thefinite-difference time domain method. It…
Wedge - Shaped Absorbing Samples Look Left Handed: The Problem of Interpreting Negative Refraction, and its Solution
M. Sanz, A. C. Papageorgopoulos, W. F. Egelhoff +3
We report experiments of light transmissivity at wavelengths: 532 and 400 nm, through an Au film with a wedge shape. Our results mimic the negative refraction reported by others fo…
Resonant radiation pressure on neutral particles in a waveguide
R. Gomez-Medina, P. San Jose, A. Garcia-Martin +3
A theoretical analysis of electromagnetic forces on neutral particles in an hollow waveguide is presented. We show that the effective scattering cross section of a very small (Rayl…
Statistical Distribution of Intensities Reflected from Disordered Media
A. Garcia-Martin, T. Lopez-Ciudad, J. J. Saenz +1
A theoretical analysis of the statistical distributions of the reflected intensities from random media is presented. We use random matrix theory to analytically deduce the probabil…
