Coherently tunable third-order nonlinearity in a nanojunction
Vadim A. Markel
A possibility of tuning the phase of the third-order Kerr-type nonlinear susceptibility in a system consisting of two interacting metal nanospheres and a nonlinearly polarizable mo…
Local anisotropy and giant enhancement of local electromagnetic fields in fractal aggregates of metal nanoparticles
Sergei V. Karpov, Valeriy S. Gerasimov, Ivan L. Isaev +1
We have shown within the quasistatic approximation that the giant fluctuations of local electromagnetic field in random fractal aggregates of silver nanospheres are strongly correl…
Superresolution and Corrections to the Diffusion Approximation in Optical Tomography
George Y. Panasyuk, Vadim A. Markel, John C. Schotland
We demonstrate that the spatial resolution of images in optical tomography is not limited to the fundamental length scale of one transport mean free path. This result is facilitate…
Experimental demonstration of an analytic method for image reconstruction in optical tomography with large data sets
Zheng-Min Wang, George Y. Panasyuk, Vadim A. Markel +1
We report the first experimental test of an analytic image reconstruction algorithm for optical tomography with large data sets. Using a continuous-wave optical tomography system w…
Multiple Projection Optical Diffusion Tomography with Plane Wave Illumination
Vadim A. Markel, John C. Schotland
We describe a new data collection scheme for optical diffusion tomography in which plane wave illumination is combined with multiple projections in the slab imaging geometry. Multi…
Comment on "Silver nanoparticle array structures that produce remarkably narrow plasmon lineshapes" [J. Chem. Phys. 120, 10871 (2004)]
Vadim A. Markel
In this Comment I discuss two incorrect statements which were made in the paper "Silver nanoparticle array structures that produce remarkably narrow plasmon line shapes" [J. Chem.…
