Also called a Split Cylinder Resonator, the system performs measurement by inserting a sheet sample between the resonators. Conforming Standards
JIS R1641,IPC-TM650 2.5.5.13
Electric Field Direction
Circularity parallel to the ground, circularity in the specimen surface (plane) direction
⇒ No confirmation of anisotropy
※It is critically important issue in development process whether there is anisotropy of materials used in electrical applications is an important development issue.
Therefore, please take the above into consideration when measuring a resin that tends to show anisotropy in the stretching or extrusion direction, or a resin composition filled with an anisotropic filler.
