Contour plots of focused electric field intensity distributions along x′ axis with zP=0 and yP=0 for OAPs with off-axis angle of (a) φ = 20.7° and (b) φ = 61.6° under tilted incidence of θx = 0.016° versus parabola f-number (f′/2R, f′ is fixed). Dashed lines present center position of electric field intensity. Intensity is indicated by color “heat”.
