Vector diffraction based on 3D Huygens-Fresnel principle and vector decomposition in Cartesian coordinate

Results in Optics
We proposed vector diffraction equations based on 3D Huygens-Fresnel principle and vector decomposition in Cartesian coordinate. Our expression should more accurate than classical Richards-Wolf diffraction, because the deduction of Richards-Wolf ...
