S052011 Analysis of the electromagnetic waves around S-S type PSJA by FDTD method

Abstract

PSJA ( Plasma Synthetic Jet Actuator ) is an electric devicc for flow control utilizing barrier discharge phenomenon ． To avoid electromagnetic interference with other devices ， it is important to anaiyze electromagnetic waves emitted by PSJA ． This paper carries out a simulation ofelectromagnetic field distribution by FDTD method using barrier discharge model ， where the electromagnetic field is assumed to be generated by discharge current between the electrodes ． The result s血ows that the electric field is directed 倉 om exposed electrode toward insulatcd elcctrodc ， and the magnetic field component
