提出了一种可在竖井之间进行地下能量传输的穿透土壤(TTS)远程无线电能传输系统。使用对原型系统的描述以及理论和实验测量来加深对该技术的理解。给出了证明Thevinin等效负载模型的测量结果，并给出了非调谐效率方程。农业传感器被用作测量土壤水分、温度和湿度的演示负载。来自传感器的数据由LORA成功记录并传输到基站。该系统能够在45米的距离内提供大约1.25W的功率。
A through the soil (TTS) long range wireless power transfer system is presented that can transfer energy underground between vertical wells. A description of the prototype system with theoretical and experimental measurements is used to develop understanding of the technology. Measurements proving a Thevinin equivalent load model are provided, and an equation for untuned efficiency. An agricultural sensor is used as a demonstration load that measures soil moisture, temperature, and humidity. Data from the sensor is successfully recorded and transmitted by LoRA to a base station. The system is capable of delivering approximately 1. 25W over a distance of 45m.
