In this paper, a one-bit coding metasurface comprised of 20 columns is proposed to achieve amplitude and phase modulation. Each column is dynamically controlled by p-i-n diodes to modulate the incident electromagnetic waves. By synthesizing the code sequence, the radar cross section (RCS) of the surface can be reduced to specific values. With shift coding and inverse code sequence, the metasurface can also achieve phase modulation function with almost the same amplitude responses. A metasurface prototype is fabricated and measured, showing an obvious RCS reduction in a 35.2% bandwidth from 7 t...
