The formation of corona discharges at high
potentials was studied. Glow coronas were found to be generated
when the electric field magnitude is in excess of 3MV/m in
general for air at atmospheric pressure. The number density of
electrons in the glow corona can only be approximated, but the
results obtained from the Boltzmann transport equation promise
to be accurate enough to give meaningful wave attenuation
results, so long as the number density is below 1019 m-3 electrons.
Above this density, the attenuation increases dramatically and
approximations for density may no longer be valid. Wave
propagation and antenna parameters in a corona plasma can be
computed through simulation using dielectric slabs of complex
impedance to simulate a plasma sheath.
