Programmable topological metasurface to modulate spatial and surface waves in real time.

ABSTRACT: We propose a programmable topological metasurface to integrate intelligent modulations of spatial and surface waves. A general design method is presented to design the programmable metasurface elements with PIN diodes. The surface waves can be controlled to propagate along the topological domain-wall interface by programming the C₃-symmetry elements, while the spatial waves are modulated by the patterns of C₆-symmetry elements. By independently controlling the bias voltages of meta-elements, the programmable topological metasurface can generate different coding patterns with distinct combinations of C₃- and C₆-symmetries in real time, respectively achieving the dynamical manipulation of the surface- and spatial-wave by using distinct element stat
