HIGHLIGHTS
- What: In this paper metal-insulatormetal copper-coin type reflective metasurfaces are proposed to generate perfect composite vortex beams in Xband. This work provides new ideas and methods for generating high-quality metasurface-based perfect composite vortex beams in the microwave region paving an ideal path for microwave communication systems optical manipulation and radar detection. The work provides a new idea and method for the modulation of the vortex field by metasurfaces in microwave band and has fabulous prospects for practical applications in wireless communication systems. The meta-atom system that the authors design can achieve efficient . . .
