Obtaining the dielectric constant of solids from capacitance measurements with a pointer electrode.
We analyze the determination of the dielectric constant of macroscopic solid samples in a nondestructive way from measurements of the capacitance between a pointer electrode and the sample's surface. We assembled an experimental device and found that an accuracy of 1% or better can be attained with common laboratory instrumentation.
