ELECTROMAGNETIC WAVE ABSORBERS |
摘要 |
<p>of the disclosure: An electromagnetic wave absorber comprising an electromagnetic wave absorbing layer consisting essentially of silicon carbide fibers, which layer may be applied to a metal plate. The wave absorber comprising the absorbing layer-applied metal plate exerts wave absorption expressed in terms of a wave attenuation which is at least 10 dB higher than the inherent attenuation caused by reflection of the wave by the absorbing layer-free original metal plate, the wave used being one which has a frequency of 8-16 GHz. Further, the silicon carbide fibers may be made into woven cloths, mat felts or the like which are laminated together and then composited with a synthetic resin or ceramics to prepare the wave absorbing layer.</p> |
