Phase-Induced Frequency Conversion and Doppler Effect With Time-Modulated Metasurfaces

Metasurfaces consisting of electrically thin and densely packed planar arrays of subwavelength elements enable an unprecedented control of the impinging electromagnetic fields. Spatially modulated metasurfaces can efficiently tailor the spatial distribution of these fields with great flexibility. Si...
