| Abstract: | Measurements based on the reflection of electromagnetic waves of frequency 9.28 ge/s from the n-type germanium samples placed in a section of wave guide were carried out, The resistivity of the samples investigated ranged from 1 ohm-cm. to 50 ohm-cm. Accurate results were obtained with a microwave reflection bridge on the samples with resistivities at the high and of the range. For the measurement of low resistivity samples, a partially filled guide system was proposed and investigated. Measurements for such a system wore found to be in dis-agreement with the theoretical modal due to the higher order modes neglected in the theoretical analysis. |
