900-MHz Nonthermal Atmospheric Pressure Plasma Jet for Biomedical Applications
A portable microwave-excited atmospheric pressure plasma jet (APPJ) using a coaxial transmission line resonator is introduced for applications of plasma biomedicine. Its unique feature includes the portability and no need for matching network and cooling system with high power efficiency, operating at 900 MHz with low ignition power less than 2.5W ...
Simulations of biomedical atmospheric-pressure discharges
The comparison between fluid and particle-in-cell simulation results in different nonthermal helium plasma sources: including an overview of kinds, strengths and limitations of the numerical models is reported. The kinetic information indicates that the electron energy probability function (EEPF) evolves from a three-temperature distribution in RF ...
Field emission and lifetime of microcavity plasma
Microplasmas with cylindrical hollow cathode have been studied by means of two-dimensional particle-in-cell/Monte-Carlo collision (PIC/MCC) simulations. For a given input power, the onset of field emission from the cathode surface caused by the strong electric field generated in these discharges leads to a reduction of the discharge voltage and an ...
Comparison of fluid and particle-in-cell simulations on atmospheric pressure helium microdischarges
Microdischarges at atmospheric pressure were studied by two computational methods. The first method is a typical one-dimensional fluid model in which the electron velocity distribution function is assumed to be Maxwellian and the energy equation is solved to determine the spatial profile of the electron temperature. The second method is a particle-...
