Hyperbolic metamaterials (HMM) are of great interest due to their ability to break the diffraction limit for imaging and enhance near-field radiative heat transfer. Here we demonstrate that an annular, transparent HMM enables selective heating of a sub-wavelength plasmonic nanowire by controlling the angular mode number of a plasmonic resonance. A nanowire emitter, surrounded by an HMM, appears dark to incoming radiation from an adjacent nanowire emitter unless the second emitter is surrounded by an identical lens such that the wavelength and angular mode of the plasmonic resonance match. Our result can find applications in radiative thermal management.
双曲线超材料（HMM）因其能够突破成像的衍射极限并增强近场辐射热传递而备受关注。在此，我们证明了一种环形透明HMM能够通过控制等离子体共振的角模数来实现对亚波长等离子体纳米线的选择性加热。被HMM包围的纳米线发射器，对于来自相邻纳米线发射器的入射辐射而言显得暗淡，除非第二个发射器也被相同的透镜包围，以使等离子体共振的波长和角模相匹配。我们的结果可应用于辐射热管理。
