Dual frequency combs are emerging as new tools for spectroscopy and signal processing. The relative phase noise of the tone pairs determines performance (e.g., signal-to-noise ratio) detected spectral components. Although previous research has shown that quality generally degrades with an increase in difference between pairs, scaling dual comb systems not been fully characterized. In this Lette...

Micro-discharges have many excellent characteristics, such as generation of high-density and non-equilibrium plasmas at atmospheric pressure. In this paper, we used an implicit particle-in-cell/Monte Carlo collision method for three-dimensional velocities in a one-dimensional space combined with the secondary electron emission model to study characteristics micro-discharges driven by dual radio...
