Plots of d_catacaustic, d_mp, d_sp and electric field intensity distributions of focused beam by OAPs under oblique incidence angles of (a) θ_x = 0.016° and (b) θ_x = 0.01° along x′ axis as a function of offset h. Fields are computed along x′ axis with zP′=0 and yP′=0 . Inset (c) shows the corresponding intensity distribution of Ex′ . Intensity is indicated by color “heat”.
