This system measures return loss and dependency of reflection phase angle on the incidence angle of TE and TM wave, and inversely calculates complex relative permittivity and complex permeability.
Unlike coaxial or waveguide type, errors by air gap do not occur because the sample is not capsulated in the fixture. Despite its compact dimensions, your sample can be measured with plane wave because the lenses are attached to the antennas, providing high measurement accuracy. Because the electromagnetic wave transmitted from the antenna is a parallel beam, your sample can be smaller than conventional systems.
εr' and μr at required frequencies are measurable.
No anechoic chamber is required.
*The higher the measurement frequency is, the smaller the size of your sample can be.
*By applying a gate beyond the lenses closer to the sample after calibration, it allows you to measure electromagnetic absorption rate above –50dB with a standard vector network analyzer.
