On Terahertz laser pulse propagation in negative index metamaterials
(BRAC University, 2013)
The nonlinear propagation of a terahertz laser pulse propagation in the resonant region of a negative index meta-material is investigated. The resonant frequency of a split ring resonator (SRR), comprosing the negative ...
Data acquisition and study of He spectrum under electric and magnetic fields
(BRAC University, 2013)
Data acquisition system for the spectrum of ionized gases is developed and the spectrum of He gas under electric and magnetic fields are studied. The results are shown through captured photographs, which shows that the ...
