High frequency sheath modulation and higher harmonic generation in a low pressure very high frequency capacitively coupled plasma excited by sawtooth waveform
Sarveshwar Sharma, Nishant Sirse, Miles M Turner
A particle-in-cell (PIC) simulation study is performed to investigate the discharge asymmetry, higher harmonic generations and electron heating mechanism in a low pressure very hig…
Driving frequency effect on discharge parameters and higher harmonic generation in capacitive discharges at constant power densities
Sarveshwar Sharma, Nishant Sirse, Animesh Kuley +2
Very high frequency (VHF) driven capacitive discharges are now being increasingly adopted for plasma-based materials processing due to their high processing rates and lower substra…
Dynamics of scrape-off layer filaments in detached conditions
David Schwörer, Nick R. Walkden, Benjamin D. Dudson +3
The here presented work studies the dynamics of filaments using 3D fluid simulations in the presence of detached background profiles. It was found that evolving the neutrals on the…
Electric field non-linearity in very high frequency capacitive discharges at constant electron plasma frequency
Sarveshwar Sharma, Nishant Sirse, Animesh Kuley +1
A self-consistent particle-in-cell simulation study is performed to investigate the effect of driving frequency on the electric field non-linearity, electron heating mechanism and…
Electric field filamentation and higher harmonic generation in a very high frequency capacitive discharges
Sarveshwar Sharma, N. Sirse, A. Sen +2
The effects of the discharge voltage on the formation and nature of electric field transients in a symmetric, collisionless, very high frequency, capacitively coupled plasma are st…
Influence of plasma background on 3D scrape-off layer filaments
David Schwörer, Nicholas R Walkden, Huw Leggate +4
This paper presents the effect of self-consistent plasma backgrounds including plasma-neutral interactions, on the dynamics of filament propagation. The principle focus is on the i…
