Advances in the field of electromagnetic metasurfaces (EMMSs) have enabled designers to yield unprecedented control over electromagnetic waves through the sophisticated matter/wave interaction facilitated by them. Encompassing a wide range of topologies, EMMSs have made it possible to design low-profile beam-forming antennas with extremely high efficiency, wide-angle refracting/reflecting surfaces, electromagnetic cloaks, and many more structures that are of major interest for wireless communications and sensing in the microwave and millimetre-wave (mm-wave) range, particularly in emerging 5G/6G wireless applications. These systems exploit a larger portion of the mm-wave frequency bands where the electromagnetic control afforded by EMMSs can be a major asset. The applicants have worked extensively on developing EMMS technology and applications through their respective research programs and collaboration at the University of Toronto. As our activities are experimentally-based, we rely extensively on measurements of the radiated characteristics of EMMSs to validate theoretical and technological concepts. To do this, we employ two near-field antenna measurement systems at the University of Toronto, which cover non-overlapping frequency ranges. The proposal seeks funding to maintain and improve this is existing infrastructure. Part of the funds requested will be used to refurbish the older microwave system, which is in need of maintenance and repair, while part allocated to supplementing the capabilities of the newer mm-wave system so that we can extend the achievable frequency range covered by this instrument. Jointly, the improvements funded by this proposal will allow us to leverage major investments made in each respective system. The measurement infrastructure used in this proposal is pivotal not only in the training of highly qualified personnel, who gain a spectrum of useful skills and experience using this equipment, but also our groups' collaborations with industry. In the latter, experimental validation of concepts is key to demonstrating the practical applications of technology and informing directions towards further commercial development. Collectively, the proposed equipment improvements will enable deep research impact in a breadth of ongoing activities in the EMMS field at the University of Toronto.

电磁超表面 (EMMS) 领域的进步使设计人员能够通过其促进的复杂物质/波相互作用对电磁波进行前所未有的控制。 EMMS 涵盖广泛的拓扑结构，使得设计具有极高效率的薄型波束形成天线、广角折射/反射表面、电磁斗篷以及更多对无线通信和通信至关重要的结构成为可能。微波和毫米波 (mm-wave) 范围内的传感，特别是在新兴的 5G/6G 无线应用中。这些系统利用了毫米波频段的大部分，其中 EMMS 提供的电磁控制可能是一项重要资产。 申请人通过各自的研究项目和与多伦多大学的合作，广泛致力于开发 EMMS 技术和应用。由于我们的活动是基于实验的，因此我们广泛依赖 EMMS 辐射特性的测量来验证理论和技术概念。为此，我们在多伦多大学采用了两个近场天线测量系统，覆盖不重叠的频率范围。该提案寻求资金来维护和改善现有的基础设施。所请求的资金的一部分将用于翻新需要维护和修理的旧微波系统，而另一部分分配用于补充较新的毫米波系统的功能，以便我们能够扩展该系统所覆盖的可实现的频率范围。乐器。共同地，该提案资助的改进将使我们能够利用在每个系统中进行的重大投资。 该提案中使用的测量基础设施不仅对于高素质人员的培训至关重要，他们使用该设备获得了一系列有用的技能和经验，而且对于我们团队与行业的合作也至关重要。在后者中，概念的实验验证是展示技术实际应用并为进一步商业开发提供方向的关键。总的来说，拟议的设备改进将对多伦多大学 EMMS 领域正在进行的广泛活动产生深远的研究影响。
