This paper presents a novel approach for generating and manipulating artificial Doppler shifts using rotational Orbital Angular Momentum (OAM) beams integrated with Space-Time Digital-Coding Reconfigurable Intelligent Surfaces (RIS). Traditional modulation schemes like Orthogonal Time Frequency Spac...
