Measurement methods
According to the microwave reflection attenuation and measurement method customized by this laboratory, this method refers to the method in the appendix [1] of the US military regulations MIL-A-17161D
* (The measurement method is not that the transmitted signal is directly in contact with the absorber)*
Measure the reflection attenuation characteristics between 3~18GHz. (Expressed in dB loss value)
Generally speaking, -3dB means 50% absorption, -6dB means 75% absorption, -10dB means 90% absorption, and -20dB means 99% absorption.
