论文摘要
为了满足物联网（IoT）中电子设备的远程和能量自我维持的通信需求，我们使用谐振光束介绍了同时的无线信息和电力传输（SWIPT）系统，该谐振光束将远程调节器纳入腔内以抑制衍射损失。我们从理论上通过望远镜内部调节器（TIM-RB）分析了谐振光束系统中的功率传递，考虑了电磁场传播，端到端（E2E）功率传递以及功率和信息接收。数值评估表明，TIM可以有效地压缩光束斑点，这使得TIM-RB可以在没有TIM处于更高功率的情况下将能量发射的两倍。此外，最大的传输距离和最大输出功率与输入功率成正比，并且在具有200W输入功率的TIM-RB中，可以实现约34m的传输距离，4W电力和12bps/Hz光谱效率。因此，TIM-RB可以被视为实现远距离，高功率和高速旋转的有前途的选择。
To satisfy the long-range and energy self-sustaining communication needs of electronic devices in the Internet of Things (IoT), we introduce a simultaneous wireless information and power transfer (SWIPT) system using the resonant beam that incorporates a telescope modulator inside a cavity for suppressing diffraction losses. We theoretically analyze power transfer in the resonant beam system with telescope internal modulator (TIM-RBS) considering the electromagnetic field propagation, the end-to-end (E2E) power transfer, and power and information reception. The numerical evaluation demonstrates that the TIM can effectively compress the beam spot, which allows the TIM-RBS to transmit energy twice as far as the RBS without TIM at higher power. Additionally, the largest transmission distance and maximum output power are proportional to the input power, and about 34m transmission distance, 4W electric power, and 12bps/Hz spectral efficiency can be achieved in the TIM-RBS with 200W input power. Hence, TIM-RBS can be considered as a promising option for realizing long-range, high-power, and high-rate SWIPT.
