Item type:Publication, Micropropulsion generation model and simulation by WGM acceleration within a Panda ring resonator system(2017-02-01) ;Siriroj, R. ;Techidheera, W. ;Phatharacom, P. ;Chiangga, S.Yupapin, P.A microbeam accelerator is modeled and simulated using the analogy of whispering gallery mode (WGM) generated by light within a nonlinear microring resonator system, which is called a Panda ring structure and made by an InGaAsP/InP material. The WGM mode is generated after the suitable ring parameters and optical input introducing into the system, especially, the suitable two nonlinear side ring radii are employed. From which, the required multiple propulsion (acceleration) of WGM beams is achieved using the multiple vertical Panda ring layout (several layers). The accelerated WGM beams of the multiple ring circuits can be obtained by the coincident of the multiple Panda rings. The simulation result shows that the proposed ring resonator system can be potentially fabricated within the microscale range and used for a microthruster, in which the required driven force can be used to drive the spacecraft or satellite to the target destination, which is known as a thrust propellant. For example, the result of the propulsion of 2.619–66.81 μN can be obtained by a single device system, which means that the larger volume or area can be used to produce more propulsion output. For further application, the suitable input source such as the infrared light source can also be used to for the micro-heat source, in which the large area of the device array may be useful for large area micro-heat source usage. © 2016 Wiley Periodicals, Inc.

Item type:Publication, Micro plasma source design using WGMs a PANDA ring(2014-01-01) ;Siriroj, R.; Yupapin, P. P.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. © (2014) Trans Tech Publications, Switzerland.
