Eripsometore method, dielectric constant and permeability measurement system

Vector network analyzer is not required, as it is a scalar measurement.
Dielectric constant compared with source and permeability compared with source can be measured the difference between TE TM wave of the reflection coefficient and amplitude ratio of the wave and phase.
Unlike coaxial tube or waveguide, and the error by the airgap doesn't occur as it doesn't put the sample in Ficscha.
It is compact size installing a lens to an antenna.
You can measure a sample by plane wave.
As the sample can be set close to the antenna, the sample will be small in size, you can read εr' and μr at frequency.
