Transmission enhancement is simulated verification based on a non-hollowing double layer of metamaterial filter.The proposed structure contains a continuous metallic film covering on a continuous dielectric layer.The simulated transmission is enhanced obviously comparing the single metal layer structure.Effects of the dielectric layer thickness and the incident angle on the transmission enhancement are simulated verification.It is found that the maximized transmittance enhancement is achieved when the thickness h1 is 20nm.Moreover,the proposed compact metal-dielectric double-layered films shows a stability of transmittance enhancement when the incident angle reaches to 45°,which can be applied in many potential fields due to its non-hollowing design strategy.%传输增强是基于非空心双层超材料滤波器的模拟验证.所提出的结构包含覆盖在连续介电层上的连续金属膜.与单金属层结构相比,模拟传输明显增强.模拟验证了介电层厚度和入射角对传输增强的影响.发现当厚度h1为20 nm时,实现了最大化的透射率增强.此外,所提出的紧凑金属-电介质双层薄膜在入射角达到45°时显示出透射率增强的稳定性,由于其非空心化设计策略,可以应用于许多潜在的领域.
