LBD-AM is an absorbing material to absorb electromagnetic waves mainly, reflection, scattering and transmission are small high-tech functional composite materials, the principle is to add electromagnetic loss in the polymer dielectric material, when the electromagnetic wave into the suction internal wave material, promote intramolecular ionic material composition, between electron movement or electronic transition, generating conductivity losses, high-frequency dielectric loss and hysteresis loss, so that the electromagnetic energy is converted into heat and dissipated to the space disappear, thereby produce absorption. The cause secondary pollution, mirror waves and surface waves have good absorption characteristics reflection does not occur.
LBD-AM吸波材料是一种以吸收电磁波为主,反射、散射和透射都很小的高科技功能性复合材料,其原理主要是在高分子介质中添加电磁损耗性物质,当电磁波进入吸波材料内部时,推动组成材料分子内的离子、电子运动或电子能级间跃迁,产生电导损耗、高频介质损耗和磁滞损耗等,使电磁能转变成热能而发散到空间消失掉,从而产生吸收作用。不发生反射而造成二次污染,对镜面波和表面波都具有良好的吸收特性。
