太赫兹操作能量收集软件定义超材料的本地化：上下文分析
Toward Localization in Terahertz-Operating Energy Harvesting Software-Defined Metamaterials: Context Analysis
摘要：
软件定义的超材料（SDM）代表了一种新的范例，实时控制的超材料。SDM被设想为在诸如智能纺织品和具有挑战性的条件下的传感等领域中实现各种令人兴奋的应用。这些应用中的许多设想SDM结构的变形（例如，滚动、弯曲、拉伸）。这影响超材料元件的相对位置，并且需要它们相对于彼此的定位。然而，如何执行这种本地化的问题尚未在社区中引发。我们认为超材料元件是通过太赫兹（THz）操作纳米网络无线控制的。此外，我们认为这些元素是能量受限的，它们唯一的动力选择是收集环境能源。对于这样的设置，我们展示了基于双向飞行时间（ToF）的定位的亚毫米精度，以及服务的高可用性（即，一致地超过80%的时间），这是定位中消耗的低能量的结果。最后，我们提供了一些相关的系统参数，如操作频率，带宽和收获率的本地化上下文。
英文摘要：
Software-defined metamaterials (SDMs) represent a novel paradigm for real-time control of metamaterials. SDMs are envisioned to enable a variety of exciting applications in the domains such as smart textiles and sensing in challenging conditions. Many of these applications envisage deformations of the SDM structure (e.g., rolling, bending, stretching). This affects the relative position of the metamaterial elements and requires their localization relative to each other. The question of how to perform such localization is, however, yet to spark in the community. We consider that the metamaterial elements are controlled wirelessly through a Terahertz (THz)-operating nanonetwork. Moreover, we consider the elements to be energy constrained, with their sole powering option being to harvest environmental energy. For such a setup, we demonstrate sub-millimeter accuracy of the two-way Time of Flight (ToF)-based localization, as well as high availability of the service (i.e., consistently more than 80% of the time), which is a result of the low energy consumed in localization. Finally, we provide the localization context for a number of relevant system parameters such as operational frequency, bandwidth, and harvesting rate.
