论文摘要
使用完全被动金属反射器的无线通信是一种有前途的技术，可用于覆盖范围扩展，提高信号，等级改善和盲区补偿，这要归功于其吸引人的功能，包括零能耗，超低成本，无信号和维护，无信号和轻松部署以及与现有无线系统的完全兼容性，以及完全兼容。但是，金属板对反射的普遍理解是基于Snell定律，即只有在观察角等于入射角时才能接收信号，仅当金属板的电尺寸极大时才有效。在本文中，我们严格地得出了一种通用反射模型，该模型适用于任何大小，任何方向和任何线性极化的金属反射器。根据金属板的雷达横截面（RC），其物理尺寸和方向向量以及波偏振和波偏转矢量，即从入射波方向变为观察方向的变化。此外，提供了基于实际现场测量结果的实验结果，以验证我们开发的模型的准确性，并使用金属反射器证明了通信的巨大潜力。
Wireless communication using fully passive metal reflectors is a promising technique for coverage expansion, signal enhancement, rank improvement and blind-zone compensation, thanks to its appealing features including zero energy consumption, ultra low cost, signaling- and maintenance-free, easy deployment and full compatibility with existing and future wireless systems. However, a prevalent understanding for reflection by metal plates is based on Snell's Law, i.e., signal can only be received when the observation angle equals to the incident angle, which is valid only when the electrical dimension of the metal plate is extremely large. In this paper, we rigorously derive a general reflection model that is applicable to metal reflectors of any size, any orientation, and any linear polarization. The derived model is given compactly in terms of the radar cross section (RCS) of the metal plate, as a function of its physical dimensions and orientation vectors, as well as the wave polarization and the wave deflection vector, i.e., the change of direction from the incident wave direction to the observation direction. Furthermore, experimental results based on actual field measurements are provided to validate the accuracy of our developed model and demonstrate the great potential of communications using metal reflectors.
