The physics of the sheath effects in monopole plasma antenna or helix plasma antenna

摘要

The magnetic field in the sheath of monopole plasma antenna or the helix antennas has been found to have a negative impact on its general functionality. The vertical and horizontal signals at predetermined angles had been compromised by the sheath effect. It was observed that this phenomenon is almost unnoticed because magnetization has the highest magnitude when the device is switch on/off. In microscopic scale (monopole plasma antenna), the sheath effect is due to femto spin demagnetization of particulates. However, in macroscopic scale (helix antenna), the sheath effect is due to signal impairment.
