Abstract

An open resonator capable of measuring dielectric characteristic of a sample having anisotropy in a dielectric constant with high accuracy. The open resonator includes two spherical reflection mirrors respectively having two reflection spherical surfaces which are arranged to face each other; and a signal injection portion for inputting an input signal used for measuring a dielectric characteristic of a sample arranged between the two reflection spherical surfaces. At least one of the two spherical reflection mirrors has a groove formed along at least one of the two reflection spherical surfaces of the at least one of the two spherical reflection mirrors.
