Dielectric metasurfaces have opened promising possibility to enable a versatile platform in the miniaturization of optical elements at visible and infrared frequencies. Due to high efficiency and compatibility with CMOS fabrication technology, Silicon-based metasurfaces have remarkable potentials for a wide variety of optical devices. Also, adding tunability feature to control the operation of metasurface benefits numerous application areas.
In this paper, we present a novel metasurface based on glide-symmetric structure. The performance of reconfigurable metasurface is based on phase modulation of transmitted wave achieved by lateral displacement of glided metasurface. The glide symmetric-metasurface is highly versatile for developing not only tunable application but also designing multifunction devices at optical frequencies.
As proof of concept, in this paper, we design and simulate a lens and beam deflector.
