摘要
利用极点展法得到的极点与留数,可对无芯片电子标签进行识别与传感。由极点与标签结构成对应关系,利用衰减因子与谐振频率可对标签结构的基本属性进行识别,还可以进一步地感知标签结构的弯曲变形程度;利用留数所含有的信息,可以感知标签结构相对入射波或观测点的空间角度方位信息。通过理论仿真分析,极点与留数不仅可用来识别标签,还可以感知标签结构的其它特性的功能。
The pole and residue approaching from SEM （singular expansion method）,which are used to identify the chipless RFID tag.The poles are uniquely associated with the chipless RFID tag.Frequency and damping factor can be used to identify an chipless RFID tag,and the degree of bend of the chipless RFID tag.The residue that can sense the tag structure compared with the incident or the space angular of the observation point.With theoretical simulation analysis,the pole and the residue not only can be used to identifiy tag,but also potential present of other characteristics perceived tag structure.
