Dynamic Temperature Profiles of Plasma Neutralization Induced by Microwave Irradiation

Abstract:

This paper investigates the thermal profiles of plasma neutralization induced by microwave radiation by the chronological examination of their thermal distributions. Single triangular, circular, and bowtie-shaped copper tapes were trimmed to investigate the plasma neutralization burst under microwave irradiation. The infrared thermal images showed that the copper tape with a more acute angle and with a narrower gap between the bowtie-shaped electrodes was inclined to generate high plasma density. A high plasma-density area was eventually observed, generating a higher temperature peak based on the experimental results. Thermal dissipation under room temperature was found critical in determining peak temperature after burst. These results may provide basis for the development of an inexpensive, microwave-induced local heating.
