| Abstract: | 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. |
