Transmission of terahertz pulses through DC glow discharge plasma was investigated for different gases. The pressure was kept in between the range of 0.1 torr-0.5 ton and for each pressure different measurements were taken at 5 mA, 10 mA and 15 mA plasma currents. Moreover, emission spectrum of Air, N(2) and Ar plasma analysis were done respectively. It was found that the transmission of terahertz pulses through nitrogen plasma was considerably affected compared to that of the argon plasma.
