A system formed by a cascade connection of meander-line strip grating
surfaces that rotates the polarization plane of a linearly polarized w
ave is reported and measured. Reflectivity measurements of the system
shaped on a reflector-backed metallic ground plane have shown reflecti
vity levels smaller than -20 dB over the 10.5-17-FHz band. (C) 1995 Jo
