By using free-space method,the absorbing properties of chiral materials with different spring concentration are measured. 利用空间测量方法对不同浓度手性旋波介质的吸波性能进行了测量。
By calculating and designing,the performance indexs of all microwave absorbate and the electromagnetic fields on all walls of a microwave darkroom are obtained. 通过计算得到了满足指定性能要求的暗室墙壁上吸波材料的吸波性能分布，以及暗室各墙壁上的总反射场强分布。
