Multifunctional Metasurfaces for Bridging Terahertz Waves in Free Space and Waveguides

Advanced Physics Research, EarlyView.
A multifunctional terahertz metasurface capable of simultaneous orthogonal polarization conversion and phase modulation is integrated onto a dielectric slab waveguide, thereby enabling efficient free‐space‐to‐guided‐wave coupling. By implementing tailored phase gradients on the metasurface, we demonstrate the formation of a focused spot within the ...
