Near-to-far field approximation of scattering by spheres: bridging the gap between the Lorenz-Mie theory and the Fresnel diffraction Open
First, we construct a faster approximation of the Lorenz-Mie theory (LMT) that is valid in both the near and far fields and for all scattering directions. Inspired by the Fresnel diffraction and the localization principle, it uses new appr…

Light tunneling and anomalous reflection from the diffraction of complex annuli: modeling the forward light scattering by spherical particles Open
Anomalous reflection and tunneling contributions of the high-frequency forward light scattering by non-absorbing spheres are modeled by the scalar diffraction of two complex annuli—one for TM and TE polarizations. Their complex radii, whic…

Numerical implementation of three-dimensional vectorial complex ray model and application to rainbow scattering of spheroidal drops Open
The rainbow patterns of oblate spheroidal drops have been observed in experiments nearly forty years ago [ Nature 312 , 529 ( 1984 ) 10.1038/312529a0 ]. However, the prediction for those complex patterns has been a challenge for convention…
