Abstract

The invention belongs to the technical field of metamaterial photonic devices, in particular to a cone-shaped hyperbolic metamaterial photonic structure and a preparation method thereof. The cone-shaped hyperbolic metamaterial photonic structure comprises, from top to bottom in turn, a cone-shaped MoO3 / Ag composite layer, an Ag film, a MoO3 dielectric layer and a glass substrate, wherein the MoO3dielectric layer has a thickness of 2nm, the Ag film has a thickness of 300nm, the cone-shaped MoO3 / Ag composite layer is composed of 2 to 3 layers of MoO3 / Ag, wherein each layer of MoO3 / Ag has a MoO3thickness of 20nm and an Ag thickness of 15nm. The invention also relates to a preparation method of the cone-shaped hyperbolic metamaterial photonic structure. The cone-shaped hyperbolic metamaterial photonic structure provided by the invention has good anti-reverse performance in a wide spectrum range of 300-1100nm.

Description

technical field [0001] The invention belongs to the technical field of metamaterial photonic devices, in particular to a conical hyperbolic metamaterial photonic structure and a preparation method thereof. Background technique [0002] Traditional light-absorbing devices are not efficient enough to convert electromagnetic energy into thermal energy, and the inherent working band of the material limits the requirements for practical applications. Surface plasmon metamaterials can significantly enhance the efficiency and bandwidth of light absorption through artificial modulation of material, structure and other parameters, breaking through the limitations of traditional technologies in principle, and are expected to play a key role in solar thermal, radiation detection, etc. . The expansion of the absorption bandwidth of the surface plasmon structure is a key scientific issue in the realization of high-efficiency light-absorbing devices, and provides basic theory and technic...
