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…
Observation of simultaneous fast and slow light
Pablo Bianucci, Chris R. Fietz, John W. Robertson +2
We present a microresonator-based system capable of simultaneously producing time-advanced and time-delayed pulses. The effect is based on the combination of a sharp spectral featu…
