Abstract

The curling probe, invented recently by Liang et al. resonates in distinctive frequencies when it is embedded in the wall of the plasma reactor. The excited frequencies of probe are studied for various electron densities. It has been demonstrated that the high-frequency volume wave resonances and the low-frequency surface wave resonances are predictable considering the wave diffraction problem from curling probe which the propagation is a combination of TE and TM modes. Resonance frequencies of probe are derived and show a good agreement with the reported study of probe inventors.
