Polarization and Space Charge Effects in Electrode Design
Abstract
Electrostatic field effects in high pressure discharges which provide physical insight into the problem of electrode design are derived. The coupled set of charge transport equations and Poisson's equation have been analytically studied using perturbation theory techniques. Our study reveals that the homogeneous field must be supplemented by the inhomogeneous contributions of space charge and polarization effects which arise from nonuniform plasma ionization and local nonconservation of each species current. The validity of a commonly used boundary condition is examined and found untenable. Implications for the computational design of electrodes are presented.
