Phase‐shifted metasurface design for pseudo‐nondiffractive beam deflection

Abstract: A transmission phase-shifted metasurface (PSM) array has been proposed for nondiffractive beam deflection. A PSM element consists of two identical semicircular rings and an I-shaped structure, which is symmetrically printed on both sides of the F4B substrate. According to the geometric optics, the phase distribution on the metasurface can be obtained. To achieve the desired phase distribution, the metasurface elements rotated at different angles are rearranged, since the phase of the transmitted wave is manipu… Show more

“…To verify the reliability of the method, we designed a monolayer metasurface absorber based on the above method. Single square ring, double square ring and cross shape with better absorption are commonly used to design metasurface structures for broadband terahertz absorbers, which have been veri ed theoretically and experimentally in many works [39]. Moreover, combining different forms of structures into a supercell is an effective way to expand the bandwidth.…”

“…Flexible processing and regulation of information can also be achieved by applying suitable coding methods for the metasurface. For example, functionalities such as beam focusing [3], deflection [4], or wavefront modulation [5] can be achieved by adjusting to the phase distribution of the metasurface. Nowadays, metasurfaces have made significant progress in various application fields, including metasurface holography [6][7][8], metalenses [9], orbital angular momentum (OAM) generators [10], and perfect absorbers [11,12].…”
