Design and analysis of beam splitter based on all-dielectric encoding metasurface
- Jinan Vocational College, Jinan, China
Metal-based beam splitters limit device efficiency. In order to improve the beam splitter efficiency and reduce the ohmic loss
of metal materials, we propose to use all-dielectric materials to design a terahertz beam splitter. Moreover, it is an effective
way to design beam splitters using all-dielectric metamaterial structures. With the rapid development of digital technology, it
is difficult for traditional analog metamaterials to digitally control electromagnetic information. We propose the use of
encoded metamaterial structures to realize the design of terahertz beam splitters. Different encoding modes can control
different scattering angles of the beam splitter. Using all-dielectric encoding metasurfaces, we design a transmissive
terahertz beam splitter and a reflective beam splitter. It is generally believed that the design of reflective beam splitters
requires a metal layer to improve the reflection efficiency, however, the loss of metal materials is also inevitable. We use the
all-dielectric encoded metamaterial structure to design a reflective beam splitter, which makes it possible to use the
all-dielectric structure to design a reflective device.
