Waves and Beams Laboratory
We carry out multidisciplinary, fundamental and applied research in physics. Our research in the recent past have included the following :
(a) Wave interaction with multicusp plasmas- Penetration and screening
- Dispersion and waves in bounded plasma with subwavelength inhomogeneities
- Birefringence and the Couton Mouton effect
- Electron plasma waves in large amplitude electromagnetic pulses
- Electron trapping in electromagnetic standing waves
- Interpulse plasma and the conventional afterglows
- Evidence of ion heating and the Buneman instability
- Physics of plasmas containing negative ions
- Evolution of electron energy distribution during genesis of breakdown plasma
- Electron random walk and the collisional cross over in presence of em waves and magnetostatic fields
- Electron random walk in presence of em waves and the difference with classical diffusion
- Momentum transfer by a focused ion beam
- Threshold energy, hysteresis, and high current ion beam guiding through a micro-glass capillary
- Ion energy distribution near a plasma meniscus
- Rapid measurement of charged particle by a current flux grating
