Time‐Varying Mosaic Metasurface Architecture Enabling Programmable Multi‐Tone Pseudo‑Doppler Spectral Engineering

ABSTRACT The pseudo‐Doppler effect, an artificial frequency shift produced by time‐varying phase modulation of stationary structures, offers a promising route for electromagnetic (EM) wave manipulation. However, existing time‐modulated metasurfaces are predominantly spatially uni...
