Spark-Induced Shockwave Dynamics Revealed via Nonresonant Four-Wave Mixing
Marios Kounalakis, Mikhail N. Shneider, Alexandros Gerakis
We report on the experimental detection of shockwave dynamics produced in a spark discharge, using a nonresonant four-wave mixing optical technique. In particular, we observe the s…
Decomposition of Methane Diluted with Inert Gas in an RF Discharge Cell
Sophia Gershman, Mikhail N. Shneider, Yevgeny Raitses
Decomposition of methane using non-thermal plasmas is an attractive route for producing hydrogen-rich gases and valuable carbon nanomaterials. Understanding how plasma discharge mo…
Thermal Radiation Exchange between Nanoparticles Heated by Arc Discharge
A. Povitsky, M. N. Shneider
The heating of particles by plasma radiation plays a critical role in space science involving dusty plasma as well as in industrial processes such as plasma vapor deposition, micro…
Frequency modulation of THz emission from a laser filament array
Sean D. McGuire, Mikhail N. Shneider
A simple traveling wave antenna model is used to theoretically study emission from an array of filaments. Both transverse and longitudinal arrays of filaments are considered. The a…
Axisymmetric model for 1-color laser filament THz emission
Sean D. McGuire, Mikhail N. Shneider
A 3D axisymmetric model for laser beam propagation in air is proposed for use with THz emission calculations. The model accounts for nonlinear propagation of the femtosecond pulse…
