This patent is example, and wave transmission rate is close to -30dB under X-band, horizontal polarization, it is reflected up in the case where no absorption
99.9%.After increasing absorbent structure, reflectivity drops to -15dB (3.2%) hereinafter, absorptivity is higher than 95%, Wo Menke
To think that he is high-selenium corn.And in other cases, such as reflectivity itself is 20% (- 7dB), it is reflected after increasing absorption
It is down to 10% (- 10dB), although absorptivity only has 3dBm, absolute absorption rate 10%, this reflectivity is reduced to RCS and brings
Apparent to improve, we are to a certain extent it is also contemplated that this is high-selenium corn.
