Measurement of the static dielectric constant of the InSb lattice via gyrotropic sphere resonances

By application of the recent solution to the interaction of an electromagnetic plane wave with a sphere of finite conductivity in a d.c. magnetic field, the resonance field positions of various microwave resonances have been utilized to provide a direct and accurate determination of the dielectric constant and carrier concentration in InSb. A value of 16.8 ± 0.2 is reported for the static dielectric constant of the InSb lattice.
