论文摘要
等离子体无线纳米链接具有很大的希望，可以克服传统金属电线的局限性，即狭窄的带宽，欧姆损耗，分散和互相词。但是，当前的发展仅限于两个固定点之间的无线通信，即具有固定接收器的固定发射器，这又限制了能效和集成水平。在这项工作中，我们建议使用磁场来进行等离子纳米antennas的辐射束转向的主动调整。在存在磁场的情况下，用严格的辐射偶极源的辐射模式显示了我们概念背后的物理原理。结果表明，在存在施加磁场的情况下，在由铁磁或高贵金属制成的等离激纳米antennas中，该方案是可行的。
Plasmonic wireless nanolinks hold great promise to overcome limitations from conventional metallic wires, namely narrow bandwidths, Ohmic losses, dispersion and cross-talking. However, current developments are limited to the wireless communication between two fixed points, i.e., a fixed transmitter with a fixed receiver, which in turn limits the energy efficiency and integration levels. In this work, we propose the use of magnetic fields for active tuning of the radiation beam steering of plasmonic nanoantennas. The physical principle behind our concept is shown with rigorous solution of the radiation pattern of a radiating dipolar source in the presence of magnetic fields. The results indicate that the proposed scheme is feasible with plasmonic nanoantennas made of ferromagnetic or noble metals in the presence of an applied magnetic field.
