WebFresnel-Kirchhoff Diffraction Formula Wide angle far field transform is based on the Fresnel-Kirchhoff diffraction formula [1]. Where R is the vector from near-field to far-field. The far-field position can be expressed with far field angle the far-field distance z=d. WebIt is the most powerful technique for studying the propagation of light in integrated optics. The method was originally introduced by Feit and Fleck in the late 1970s [1]. The BPM was initially based on FFT algorithm. Later on it has been extended to finite-difference based BPM schemes (FD-BPM) and finite-element BPM (FE-BPM) and many others. candibod fitness
