Abstract
The technique for measuring the low-frequency ac mobility of free surface charges first employed by Sommer is analyzed for arbitrary values of driving frequency, charge mobility, and effective mass. Analytical expressions for the cell admittance are given for both rectangular and circular geometries in the absence of edge corrections.
