Efficient Light Bending with Isotropic Metamaterial Huygens’ Surfaces

Metamaterial Huygens’ surfaces manipulate electromagnetic wavefronts without reflection. A broadband Huygens’ surface that efficiently refracts normally incident light at the telecommunication wavelength of 1.5 μm is reported. The electric and magnetic responses of the surface are independently cont...

Description
Summary:Metamaterial Huygens’ surfaces manipulate electromagnetic wavefronts without reflection. A broadband Huygens’ surface that efficiently refracts normally incident light at the telecommunication wavelength of 1.5 μm is reported. The electric and magnetic responses of the surface are independently controlled by cascading three patterned, metallic sheets with a subwavelength overall thickness of 430 nm. The peak efficiency of the device is significantly enhanced by reducing the polarization and reflection losses that are inherent to earlier single-layer designs.
