| Abstract: | The rigorous electro-magnetic diffraction theory of nonparaxial vectorial beam is proposed and illustrated by the diffraction of nonparaxial vectorial Gaussian beam diffracted at a slit. A numerical comparison with the analytical expressions based on the vectorial Rayleigh-Sommerfeld diffractiion integrals is given to show the consistency between them. A futher extension of the theory is briefly discussed. |
