Overview
Rubber Sheet Microwave Absorbers
We supplies Rubber absorbers in sheet form, default is neoprene rubber, for higher working temperature -50°C ~ + 180°C or -85°F ~356°F ), silicon rubber is recommended. And also nitrile rubber is available for resitance to water and oil.
Standard working frequency is 15GHz, 10, 9.4, 5.5, 3 and 2GHz. At the tuned
frequency, attenuation could achieve –17~-25dB in normal incidence, and down to –13dB and –10dB in the range of 24% and 35% bandwidth. For off normal, attenuation change little for small incidence and at 60°, vertical polarization goes to –7dB and horizontal polarization goes to –13dB.
