EAS03 is an ideal solution for evaluations of the electric wave absorbers and shield materials.
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.
Samples can be smaller than conventional systems because they can be placed in the vicinity of the antennas.
It is also suitable for ITS/ETS applications. It also supports a vertical incidence when using a vector network analyzer.
Transportable type is available for heavy or immovable objects such as concrete wall or asphalt road.

* The higher the measurement frequency is, the smaller the samples 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.
