Millimeter-wave～Terahertz-wave Compatible Absorber Sheet（Under Development）
EMW absorber sheet applicable to high frequency band
(Millimeter-wave – Terahertz-wave)
Under development to meet with future demand for EMC at high frequency band (Beyond 5G）
- EMW absorber of reflection type compatible at terahertz-wave band with high attenuation rate of 99％ or more
- EMW absorber sheet with transparency
(transmittance : approx.60％) - It is possible to control absorption frequency.
- Flexible sheet and easy to follow
- Adhesive layer to attach easily on the target.
