极端环境中的许多重要应用都需要无线通信来连接智能设备。超材料增强磁感应（M2 I）由于其在有损介质中的长通信范围而被提出作为一种有前途的解决方案。$M $2I通信依赖于磁耦合，这使得它本质上是全双工的，没有自干扰。此外，工程有源超材料提供了通信范围和干扰的可重构性。在本文中，新的网络范式的基础上，可重构和全双工$M $2I通信技术进行了研究。特别地，首次提供了理论分析和电磁仿真来证明其可行性。然后，提出了一种避免冲突的媒体访问控制协议。最后，推导了全双工M2 I网络的容量和延迟，以显示新的组网模式的优势。本文的分析表明，在全双工$M $$2I网络中，源和目的地之间的距离可以是任意长的，端到端的延迟可以短到单跳延迟。因此，这种网络中的每个节点可以通过一跳到达任何其他节点，这可以大大提高网络的鲁棒性和效率。它对于紧急信息或实时控制信号的及时传输非常重要。
Many important applications in the extreme environment require wireless communications to connect smart devices. Metamaterial-enhanced magnetic induction (M2I) has been proposed as a promising solution thanks to its long communication range in the lossy medium. $M$ 2I communication relies on magnetic coupling, which makes it intrinsically full-duplex without self-interference. Moreover, the engineered active metamaterial provides reconfigurability in communication range and interference. In this paper, the new networking paradigm based on the reconfigurable and full-duplex $M$ 2I communication technique is investigated. In particular, the theoretical analysis and electromagnetic simulation are first provided to prove the feasibility. Then, a medium access control protocol is proposed to avoid collisions. Finally, the capacity and delay of the full-duplex M2I network are derived to show the advantage of the new networking paradigm. The analysis in this paper indicates that in a full-duplex $M$ 2I network, the distance between the source and destination can be arbitrarily long and the end-to-end delay can be as short as a single hop delay. As a result, each node in such network can reach any other node by one hop, which can greatly enhance the network robustness and efficiency. It is important for timely transmission of emergent information or real-time control signals.
