Abstract

This paper presents a novel wireless power and information transfer (WPIT) in a closed space utilizing frequency selected surfaces (FSSs). The framework of a greenhouse or a building can be considered as the FSSs. Therefore, the frequency of the power provided to the sensors can be confined inside the frame-work and a communication frequency to the sensor can be transmitted and received from the outside. The concept using a metal mesh box with a shelf is demonstrated. First, it is confirmed that the power transfer frequency can be confined inside the box by S-parameters from port 1 to each received port and the electric field standing wave in the box. Then, it is demonstrated that the power can be transferred to the Line-Of-Sight (LOS) and Non-Line-Of-Sight (NLOS) sensors in the metal mesh box and the sensing data can be received outside the box.
利用频率选择表面在封闭空间中进行无线供电和信息传输
提出了一种利用频率选择面(fss)实现封闭空间无线供电和信息传输的新方法。温室或建筑物的框架可以被视为fss。因此,提供给传感器的电源频率可以限制在框架内部,并且可以从外部发送和接收到传感器的通信频率。演示了使用带架子的金属网盒的概念。首先,通过端口1到每个接收端口的s参数和箱体内的电场驻波,确定了功率传输频率可以限定在箱体内。然后,证明了功率可以传输到金属网盒内的视距(LOS)和非视距(NLOS)传感器,并且可以在盒外接收传感数据。
