Frequency-modulated continuous-wave laser distance measurement system using Fabry- Perot cavity as measuring reference
Guang Shi, Kefei Hei, Wen Wang +1
Frequency-modulated continuous-wave (FMCW) is a ranging technique that allows for high precision distance measurement over long distances. Scanning nonlinearity and range of the tu…
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…
Distance measurement in air without the precise knowledge of refractive index fluctuation
Morris Cui, Steven A. van den Berg, Nandini Bhattacharya
The accuracy of long distance measurement in air is limited by the fluctuation of refractive index. In this paper, we propose a technique which allows us to measure an absolute dis…
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…
