Summary
To solve the low transmission rate or disruption caused by the non-line of sight and multi-path transmission in indoor or outdoor environment, a special electromagnetic surface is designed to guide the beam to the desired area with multiple reflections.
Scientific Breakthrough
電磁面鏡的設計中,最主要的應用原則為捕捉電磁波並重新導引之。其實現大多採用印刷電路,並且無須任何電源功耗(零功耗)。相較於基站或強波器的建置,電磁面鏡的設計將為毫米波頻段的電磁波,在空間中更有效的被使用。主要解決的問題有二:一、電磁波經由面鏡反射/透射以後,電磁波的能量更加聚焦,使其即便在毫米波頻段也可以有較遠的傳輸距離;二、透過設計,可以使電磁波指向所需要的方向,也就是空間電波”再分布” (re-distribution)的概念。
相較於小型基站,除了建置成本相對低廉,並且擁有零功耗等好處,目前尚未有足夠的數據以評估實際的量化數值,例如佈建成本減少量,能源使用效率提升量,頻譜使用效率提升量等量化數據,此種評估數據需要進行多方模擬和大數據運算,佈建成本的估算需考量實際市場營運狀況。
Industrial Applicability
The construction of future 5G system will cost a lot if thousands of small cell base stations are arranged. The cooperation of electromagnetic surface and small cell base station can effectively guide the signal to multiple RF dark zones. It will enhance the efficiency of space using and energy.
