Figure 3
The merit flux of EPBM (1 mrad horizontal angular acceptance and 0.1% bandwidth) with corresponding circular polarization rates. The solid curves are for merit flux with a fixed vertical slope of 0.50 mrad and with vertical angular acceptances of 0.33, 0.66 and 0.99 mrad. The point curve indicates the optimal merit flux for 0.50 mrad vertical angular acceptance. |
