以往傳統EMI (Electromagnetic Interference) 雜訊主要以傳導為主。隨著電子技術迅速發展,電子類產品和行動通訊設備逐漸朝向微小化以及高速處理發展,電路的佈局越來越緊密與複雜,元件以及走線之間的距離縮小,造成許多敏感電路受到干擾,使得電路的效能減低或產生誤動作。而在現今社會中無線通訊設備越來越多,未來還會有「物聯網」與「車聯網」的環境加入,因此設備與設備彼此之間的輻射干擾也將會日益嚴重。

而現今在許多元件上也會採用屏蔽材料來降低輻射干擾,本論文主要參考國際電工委員會(International Electrotechnical Commission )的IEC 61967-6磁場探棒和美國材料與試驗協會(American Society for Testing and Materials ) 的ASTM D4935-99 Coaxial cell來量測電磁屏蔽材料之屏蔽效能,並且使用電磁模擬軟體來對磁場探棒與同軸纜線進行模型建置,以及探討屏蔽材料於近場與遠場的效率關聯性。最後,針對WPC 1.1標準設計無線充電耦合線圈,比較將磁性屏蔽材料置於線圈間的影響差異來顯示其耦合效率。

In the past, traditional EMI (Electromagnetic Interference) noise mainly dominated by conduction. With the rapid development of electronic technology, the electronic products and mobile communication equipment gradually develop into miniaturization and high speed processing. The circuit layout has also becoming more and more crowded and complex, resulting in narrowing of distances between elements and lines. These in turn causes interferences between sensitive circuits affecting the circuit performance or even malfunction. Nowadays, there are more and more wireless communication equipment. In the future, “Internet of Things, IoT” and “Internet of Vehicles, IoV” will surround our life. Therefore, radiation interference between equipment will worsen progressively.

Nowadays, we will also use shielding materials to reduce radiation interference on elements. This article referred to the International Electrotechnical Commission (IEC 61967-6 Magnetic Probe) and American Society for Testing and Materials (ASTM D 4935-99 Coaxial cell) the standards to measure the effectiveness of electromagnetic shielding materials. This article also mentioned that using electromagnetic simulation software to design Magnetic Probe and Coaxial Cell model, and investigated the efficiency relation of shielding materials in near field and far field. Finally, using the WPC 1.1 standard to design a wireless charging coupling coil to compare the coupling efficiency when the shielding material put on the coil.
