Reflectivity of electromagnetic wave absorbers in millimetre wave frequency - Measurement methods

This International Standard specifies the measurement methods for the reflectivity of electromagnetic wave absorbers (EMA) for the normal incident, oblique incident and each polarized wave in the millimetre-wave range. In addition, these methods are also equally effective for the reflectivity measurement of other materials: - measurement frequency range: 30 GHz to 300 GHz; - reflectivity: 0 dB to –50 dB; - incident angle: 0° to 80°.
