(a) Top: the isophotes near the focus calculated by BPM when σ = 0.2 nm, where Δz and Δx are parallel and transverse to the incident beam. Bottom: the isophotes near the focus calculated by our approach when σ = 0.2 nm. (b) The intensity profiles on the best focal plane calculated by BPM and our approach when σ = 0.2 nm. The black line is calculated by BPM. The red line is calculated by our approach.
