摘要： A novel wireless feed system is described which employs a plasmonic surface that is excited by one or more antennas. The plasmonic surface produces replicated currents within a plurality of cell elements that are closely-spaced electrically, e.g., compared to an operational wavelength. The cell elements are preferably substantially fractal in shape for at least a portion of their geometry, and at least a first iteration of a motif on that portion. Such a plasmonic surface may be a single sheet or a looped manifold "shell." The cells of such a plasmonic surface act to deliver radiation, or conversely, receive radiation-without the use of direct electrical connections-due to the evanescent surface wave effect, r plasmonic transmission. This delivered radiation may accordingly be near-field coupled to an adjacent antenna, antenna array, or another plasmonic surface used as an antenna array.

摘要： In an inductively coupled radio frequency identification (RFID) system deployed in animal and livestock applications, reading system efficacy can be compromised by animal movement on, around, or near metal structures prone to producing sonic frequencies. Such is the case, for example, when a walk-by antenna is mounted at the entry door of a livestock transport trailer, and animals transit on a metallic ramp and metallic trailer floor. Associated with the observable acoustic noise are subtle disturbances in the magnetic field surrounding the antenna due to vibrating metal altering the reluctance of the antenna's magnetic field. This acoustic noise manifests itself as an electrical noise phenomenon that interferes with the signals of certain types of identification tags which rely on amplitude modulation. The detrimental effects of acoustic noise from metal structures can be mitigated by using a multi-loop antenna that limits the spatial distribution of the transmitted magnetic field and cancels close by magnetic field disturbances.
摘要翻译：在动态和家畜应用中的电感耦合射频识别（RFID）系统中，阅读系统功效可能会受到容易产生声音频率的金属结构，周围或附近的动物运动的影响。例如，当将步行天线安装在牲畜运输拖车的入口处，并且动物在金属斜坡和金属拖车地板上转运时。与可观察到的声学噪声相关联是由于振动金属改变天线磁场的磁阻而在天线周围的磁场中的微小干扰。这种声音噪声本身表现为电噪声现象，其干扰依赖于幅度调制的某些类型的识别标签的信号。可以通过使用限制发射磁场的空间分布并通过磁场干扰来抵消的多环天线来减轻来自金属结构的声学噪声的有害影响。
