Fig. 2From: Sheath capacitance observed by impedance probes onboard sounding rockets: Its application to ionospheric plasma diagnosticsCalculated equivalent probe capacitance. Plasma parameters are set as fpe = 3.0 MHz, fce = 1.4 MHz, f ν = 0.05 MHz, and the static magnetic field is perpendicular to the probe axis. The solid line represents calculation including the sheath capacitance of Cs = 30 pF. Dashed line shows equivalent probe capacitance of only the plasma region.Back to article page
