In this study, we have developed the high-Q microwave dielectric cavity, which can generate circularly polarized eigenmodes. It can maintain a high-Q value even in a high magnetic field, and the circular dichroism allows us to evaluate the conductivity susceptibility and impedance tensor, including the off-diagonal term. In this talk, we will present our developed cavity and the results of Hall effect measurements in the microwave region by surface impedance tensor measurements.
