The focusing theory of electromagnetic waves has been well developed. A scalar wave theory satisfactorily describes the focusing process for a small semi-aperture angle. However, the vectorial charact...
We theoretically investigate the tight focusing properties of hybridly polarized vector beams. Some numerical results are obtained to illustrate the intensity, phase, and polarization of tightly focus...
Based on vectorial Debye theory, the focusing properties of partially polarized vortex beam by high numerical aperture Fresnel zone plate are investigated. The effects of the numerical apertures of an...
The properties of a pair of vortices embedded in a Gaussian beam focused by a high numerical-aperture are studied on the basis of vector Debye integral. The vortices move and rotate in the vicinity of...
We study the focusing properties of a double-ring-shaped azimuthally polarized beam through an annular high NA objective lens. It is shown that a subwavelength focal hole (~ 0:5λ) with a quite long de...
We study the tight focusing properties of partially coherent, partially polarized vortex beams through a high numerical aperture (NA) objective. The influence of the degree of polarization,the topolog...
Based on the vectorial Debye theory, the tight focusing properties of partially coherent and circularly polarized vortex beams are investigated. The focused characteristics of right-circular and left-...
