项目摘要

The MetaMagIC project addresses current technological concerns about the energy efficiency and sustainability of magnetic devices in Information and Communication Technology systems. To increase the efficiency of these there is a strong drive to achieve the precise control of magnetic fields on much smaller microscopic length scales in order to concentrate them uniformly in small and targeted regions. There is also a need to move away from expensive rare-earth based magnetic materials whose supply could become uncertain in the near future. MetaMagIC offers a low cost and highly effective way to address both these key challenges in a ground-breaking approach based on spatially structured magnetic materials, so-called magnetic metasurfaces. Combining cutting-edge theory and modelling with state-of-the-art techniques for fabricating and characterising magnetic thin-film devices, we will address several important technological areas. We will greatly increase the sensitivity of magnetic sensors, such as those found in cars and smart meters, by incorporating them in specially designed planar metasurfaces. We will also use this approach to improve the efficiency of small energy harvesting structures that can extract enough energy from their environments to power small electronic devices. We will combine the field expulsion and concentration properties of metasurfaces to achieve much more efficient wireless charging of, for example, mobile phones. Finally we will use the high field saturation of the response of magnetic materials to design entirely new types of devices and protect very sensitive equipment like heart pacemakers from damage by high magnetic fields.

MetaMagIC 项目解决了当前信息和通信技术系统中磁性设备的能源效率和可持续性的技术问题。为了提高这些效率，需要在更小的微观长度尺度上实现磁场的精确控制，以便将它们均匀地集中在小目标区域。还需要放弃昂贵的稀土磁性材料，这些材料的供应在不久的将来可能会变得不确定。 MetaMagIC 提供了一种低成本且高效的方法，以基于空间结构磁性材料（即所谓的磁性超表面）的突破性方法来解决这两个关键挑战。将尖端理论和建模与制造和表征磁性薄膜器件的最先进技术相结合，我们将解决几个重要的技术领域。我们将通过将磁传感器（例如汽车和智能电表中的磁传感器）整合到专门设计的平面超表面中，极大地提高它们的灵敏度。我们还将使用这种方法来提高小型能量收集结构的效率，这些结构可以从环境中提取足够的能量来为小型电子设备供电。我们将结合超表面的场排斥和集中特性，以实现更高效的无线充电，例如手机。最后，我们将利用磁性材料响应的高磁场饱和度来设计全新类型的设备，并保护心脏起搏器等非常敏感的设备免受高磁场的损坏。
