Abstract

A nulling bridge-type dispersive interferometric spectrometer has been constructed to measure complex refractiveindices of solids in the millimeter wave region. The complex refractive indices of doped Si and GaAs wafers are obtained in the110 - 170 GHz region and their dispersion is analyzed based on the Drude model. The electrical resistivity estimated from theDrude-model fitting agrees well with that measured by the dc four-point probe method.
