Abstract
When spacecrafts come back into the atmosphere, the heat caused by the friction of the high-speed spacecrafts and atmosphere will induce the plasma. The plasma will interrupt the communication between spacecraft and ground. Aiming at the problem, in this paper, the plasma was produced by DC glow discharge. We achieved the plasma with the same concentrations as black barrier plasma and tested the free transmission of terahertz wave in plasma.
