Dynamic Mode Decomposition of inertial particle caustics in Taylor-Green flow
Omstavan Samant, Jaya Kumar Alageshan, Sarveshwar Sharma +1
Inertial particles advected by a background flow can show complex structures. We consider inertial particles in a 2D Taylor-Green (TG) flow and characterize particle dynamics as a…
An enhanced operating regime for high frequency capacitive discharges
Sanket Patil, Sarveshwar Sharma, Sudip Sengupta +2
We report the existence of an enhanced operating regime for a high-frequency, low-pressure capacitively coupled plasma (CCP) discharge in the presence of a weak magnetic field appl…
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…
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…
