Plasma is a one of state of matter that is produced by applying energy into gas or fluid like, where the ionized electrons from gas or fluid atoms to be free electrons. In this paper, the use of micro plasma source generation by using a PANDA ring resonator is introduced, in which the whispering gallery modes (WGMs) are formed within the center ring and can be used to create the high power of electromagnetic wave for gas plasma production. In application, the micro plasma source can be fabricated in small scale material process or others suitable operation. In this case, the plasma source can be decreased to be micro-scale device, where in fact, the common plasma source system size is large because the high energy source to produce high power plasma is required. Finally, the detail of using such small scale plasma source is discussed. The theoretical details of whispering gallery mode and quantum tunneling effects are also reviewed and discussed.

Radio frequency (RF) circuit elements that are traditionally considered to be linear frequently exhibit nonlinear properties that affect the intended operation of many other RF systems. Devices such as RF connectors, antennas, attenuators, resistors, and dissimilar metal junctions generate nonlinear distortion that degrades primary RF system performance. The communications industry is greatly affected by these unintended and unexpected nonlinear distortions. The high transmit power and tight channel spacing of the communication channel makes communications very susceptible to nonlinear distortion. To minimize nonlinear distortion in RF systems, specialized circuits are required to measure the low level nonlinear distortions created from traditionally linear devices, i.e., connectors, cables, antennas, etc. Measuring the low-level nonlinear distortion is a difficult problem. The measurement system requires the use of high power probe signals and the capability to measure very weak nonlinear distortions. Measuring the weak nonlinear distortion becomes increasingly difficult in the presence of higher power probe signals, as the high power probe signal generates distortion products in the measurement system. This paper describes a circuit design architecture that achieves 175 dB of dynamic range which can be used to measure low level harmonic distortion from various passive RF circuit elements.
