On collisions driven negative energy waves and Weibel instability of a relativistic electron beam in a quasi-neutral plasma
Anupam Karmakar, Naveen Kumar, Gennady Shvets +2
A new quasi-neutral model describing the Weibel instability of a high-current relativistic beam propagating through a resistive plasma is developed. It treats beam electrons as kin…
Three dimensional filamentary structures of a relativistic electron beam in Fast Ignition plasmas
Anupam Karmakar, Naveen Kumar, Oleg Polomarov +2
The filamentary structures and associated electromagnetic fields of a relativistic electron beam have been studied by three dimensional particle-in-cell (PIC) simulations in the co…
Wide-angle infrared absorber based on negative index plasmonic metamaterial
Yoav Avitzour, Yaroslav A. Urzhumov, Gennady Shvets
A metamaterials-based approach to making a wide-angle absorber of infrared radiation is described. The technique is based on an anisotropic Perfectly Impedance Matched Negative Ind…
Polarization conversion in a silica microsphere
Pablo Bianucci, Chris Fietz, John W. Robertson +2
We experimentally demonstrate controlled polarization-selective phenomena in a whispering gallery mode resonator. We observed efficient () polarization conversion of…
Guiding, focusing, and sensing on the sub-wavelength scale using metallic wire arrays
G. Shvets, S. Trendafilov, J. B. Pendry +1
We show that two-dimensional arrays of thin metallic wires can guide transverse electromagnetic (TEM) waves and focus them to the spatial dimensions much smaller that the vacuum wa…
