Adding a spin to Kerker's condition: arbitrary scattering direction tuning of nano-antennas with designed excitation
Lei Wei, Nandini Bhattacharya, H. Paul Urbach
We describe a method to control the directional scattering of a high index dielectric nanosphere, which utilizes the unique focusing properties of an azimuthally polarized phase vo…

Excitation of radiationless anapole mode of isotropic dielectric nanoparticles with tightly focused radially polarized beam
Lei Wei, Zheng Xi, Nandini Bhattacharya +1
A high index dielectric nano-sphere can be excited and yet remain radiationless. A method to excite the non-radiating anapole mode of a high index isotropic dielectric nanosphere i…

Shaping the focal field of radially/azimuthally polarized phase vortex with Zernike polynomials
Lei Wei, H. Paul Urbach
The focal field properties of radially/azimuthally polarized Zernike polynomials are studied. A method to design the pupil field in order to shape the focal field of radially or az…
