Angle of incidence change method
dielectoric constant, dielectric loss tangent, permeability
measurement system

Catalog No. dps22002040516-08

Return loss and reflection phase angle of incidence angle dependence TE waves and TM waves measured.
Estimated readings from the reverse of the complex dielectric constant and complex permeability is determined.
The error by the airgap doesn't occur, because the measurement system doesn't put the sample in Ficcha, unlike the coaxial tube type or waveguide type.
The antenna can be mounted on the lens, compact even though the plane wave samples can be measured, the accuracy of measurements.
You can make a small sample, because the electric wave which came out of an antenna is parallel.
ε r ',μ r ,each frequency is understood.
* No darkroom can be measured.
