Experimental characterization of test devices. (a) Shows measured spectrum for design A at different periods and (b) shows the same for design B. (c) Depicts the angle dependence at peak period for design A and (d) shows the same for design B. The thin lines are the raw data and the thick lines represent a polynomial fit.
