Characterization of Broadband Focusing Microwave Metasurfaces at Oblique Incidence
Ashif A. Fathnan, Toufiq M. Hossain, Dadin Mahmudin +2
We report the characterization of an achromatic focusing metasurface at oblique incident angles. We show that in addition to the inherent off-axis aberrations that occurs due to th…
