Anomalous Surface Wave Launching by Handedness Phase Control

Adv Mater. 2015 Nov 25;27(44):7123-9. doi: 10.1002/adma.201502008. Epub 2015 Oct 9.


Anomalous launch of a surface wave with different handedness phase control is achieved in a terahertz metasurface based on phase discontinuities. The polarity of the phase profile of the surface waves is found to be strongly correlated to the polarization handedness, promising polarization-controllable wavefront shaping, polarization sensing, and environmental refractive-index sensing.

Keywords: near-field microscopy; phase discontinuities; surface waves; terahertz metasurfaces.
