TM mode Cavity Resonator
Cutting machine for film (Optional Item)
TM mode Cavity Resonator measures strip-shaped samples.
The high Q factor resonator enables the stable measurement with high resolution of low dielectric loss materials such as PTFE and high-purity ceramics.
This method is compliant with JIS C2565, ASTM D2520.
Use

Feature: TM mode Cavity Resonator
TM mode cavity resonator uses the TM resonant mode (TM010 / 011), where the electric field vector is parallel to the rotational axis of the cylindrical cavity.
By inserting the measurement sample along with the center axis of the cylinder, the resonance changes according to its dielectric constant.
Shape and size of sample
The shape of the measurement sample is a strip. The dielectric constant in the longitudinal direction of the strip is measured.
Cutting machine for film (Optional Item)
The dedicated cutting machine is available for film materials (thickness is 0.2mm or less).
