Abstract :
An open-resonator system is constructed for the precision dielectric permittivity and loss-tangent measurement of low-absorbing materials at 60 GHz. In this new inexpensive simple system, only one frequency source is used together with a liquid helium-cooled InSb detector for the full cavity-length variation technique. This new simple open resonator system provides data with high measurement accuracy although it only uses one fixed frequency source.
