Dear sir 

its basically under the normal incidence of light. We have used rotation of nanobars under Pancharnam Berry phase concept to realize inplane rotation of nanobars of same dimensions to develop a metasurface.But when we find FWHM Full width half maximum for the spot located at 0deg that is bit compromized rather than the spot focused at 90 degree.
