摘要
首先介绍了国内外的几种微波衰减材料,同时分析了我所正在使用和研究的几种衰减瓷;其次介绍了波导传输反射法测量微波衰减材料的高频电磁参数,以及国内其它单位和国外的测量水平状况;再次,通过介绍衰减器微波吸收特性的CAD,对衰减瓷在使用中的不匹配问题进行了讨论;最后结合笔者的认识,讨论了今后微波管用衰减材料的研究方向。
Several microwave attenuating materials used in MWTs were introduced and their properties were described in detail. In addition, measurement of the electromagnetic properties of microwave attenuating materials by the transmission/reflection method was introduced, and the current measurement status over nation and foreign were showed. In order to achieve favorable matching between microwave attenuating materials and MWTs, CAD of the attenuating materials in MWTs can be carried out. Finally, further investigations of microwave attenuating materials used in MWTs were pointed out.
