| Abstract: | In Chinese.Double layer EM wave absorption boards (100 mm×100 mm) are manufactured from th ree kinds of ferrite EM wave absorption materials of different permeability. In the range of 8～12 GHz, transmission properties are absorption quantity A _t =12.2 dB when coating thickness is 1.80 mm and A _t>9 dB when coating thickness in the range of 1.15～1.85 mm, and reflection properties are absorption quantity A _f=23 dB, 10 dB bandwidth is 4 GHz, matching thickness is 1.17 mm . Cheap EM wave a bsorption boards will be widely used.(3 refs.) |
