Method for measuring complex dielectric constant or complex magnetic constant of materials in three-dimensional directions |
摘要 |
Method for measuring complex dielectric or magnetic constant of materials in three-dimensional directions comprising the steps of: inserting a specimen held by a rotary holder into a slit which is provided in such a position corresponding to the antinode or belly portion of electric or magnetic field of a cavity resonator that the slit fully turns around the four-side walls of the cavity resonator in a plane perpendicular to the axis thereof to rotatably accommodate the holder about the axis; measuring the respective resonant frequencies f1 and f2 and the respective Q-values Q1 and Q2 of the cavity resonator before and after inserting said specimen into the split; and calculating the complex dielectric or magnetic constant for each of some rotation angles of the holder and each of some insertion dispositions of the specimen to the holder.
