Abstract The open resonator method for dielectric measurements is developed in the submillimeter-wave region. This method, different from usual laser methods is based on the sweeping of resonator length. The conventional theory developed in the millimeter-wave region is improved so as to make measurements possible with resonable precision even in this frequency region and the design criterion of an optimum resonator at around 890 GHz (λ0=337μm) is presented. Finally, the measurements are performed for several kinds of low loss material and it is confirmed that the present method becomes a useful one in the submillimeter-wave region.
