The consumer electronic and telecommunication sectors continue to grow as the demand and utilization of mobile and smart devices continue to expand. At the same time, there is an increasing urge and demand on electromagnetic interference (EMI) shielding of radio frequency radiation for our society. EMI shielding is required to protect us, our environment, and our workspace from radiation coming from telecommunication equipment and computers. Electrically-conductive polymer composites are one of the most promising materials for this application due to their light weight, resistance to corrosion, flexibility, and processing advantages. To fabricate electrically-conductive polymer composites with tailored properties, precise measurement of EMI shielding effectiveness and electromagnetic parameters (permittivity, permeability, and loss tangent) of materials over ultra-high frequency ranges (radio frequencies) is crucial and highly challenging.

随着移动和智能设备的需求和使用不断扩大，消费电子和电信行业持续增长。与此同时，社会对射频辐射电磁干扰（EMI）屏蔽的迫切要求和需求也日益增加。需要 EMI 屏蔽来保护我们、我们的环境和工作场所免受电信设备和计算机的辐射。导电聚合物复合材料因其重量轻、耐腐蚀、柔韧性和加工优势而成为该应用中最有前途的材料之一。为了制造具有定制特性的导电聚合物复合材料，在超高频率范围（射频）内精确测量材料的 EMI 屏蔽效能和电磁参数（介电常数、磁导率和损耗角正切）至关重要且极具挑战性。
