Space-Time Modulated Metasurfaces with Spatial Discretization: Free-Space N-path Systems
Zhanni Wu, Cody Scarborough, Anthony Grbic
This work theoretically and experimentally studies metasurfaces with spatially-discrete, traveling-wave modulation (SD-TWM). A representative metasurface is considered consisting o…

Serrodyne frequency translation using time-modulated metasurfaces
Zhanni Wu, Anthony Grbic
Temporally modulated metamaterials have attracted significant attention recently due to their non-reciprocal and frequency converting properties. Here, a transparent, time-modulate…
