We reveal an outstanding potential of water as an inexpensive, abundant and bio-friendly high-refractive-index material for creating tunable all-dielectric photonic structures and metamaterials. Specifically, we demonstrate thermal, mechanical and gravitational tunability of magnetic and electric resonances in a metamaterial consisting of periodically positioned water-filled reservoirs. The proposed water-based metamaterials can find applications not only as cheap and ecological microwave devices, but also in optical and terahertz metamaterials prototyping and educational lab equipment.
我们揭示了水作为一种廉价、丰富且对生物友好的高折射率材料在创建可调谐全介质光子结构和超材料方面的巨大潜力。具体而言，我们展示了在由周期性排列的充满水的储液器组成的超材料中，磁谐振和电谐振的热、机械和重力可调谐性。所提出的水基超材料不仅可以用作廉价且环保的微波器件，还可应用于光学和太赫兹超材料原型制作以及教育实验室设备。
