Description
Summary:Terahertz electromagnetic waves are widely used in various fields, but their practical application often suffers from significant interfacial losses. In this paper, we present a terahertz antireflection film based on an all-dielectric metasurface consisting of a zirconia microsphere array assembled using a template-assisted method. Simulations and experiments show that the film has a broadband, outstanding transmission-enhancing effect. Because the antireflection film has the advantages of ultralow cost, high compatibility, flexibility, and easy industrialization, it may have potential applications in various fields.
