SEARCH FOR RESONANCE BEHAVIOR IN THE MICROWAVE DIELECTRIC CONSTANT OF GaAs

In a recent communication, Larrabee and Hicinbothem presented measurements of the dielectric constant of high‐resistivity GaAs showing a region of anomalous dispersion centered at 9.5 GHz. We have made similar measurements over the frequency range between 8.5 and 70 GHz but have not obtained their results. Our measurements indicate that the relative dielectric constant is independent of frequency in the microwave range and equal to 12.95 ± .10 at room temperature.
