| סיכום: | Title screen We present a full-wave frequency-domain finite-difference framework for near-field scattering of structured light by rotating infinite cylinders with arbitrary cross-sections. Rotation is incorporated through a Minkowski-type motional-coupling term embedded directly into the discrete Maxwell operators. This treatment allows non-canonical profiles and structured illuminations to be modeled within a frequency-domain full-wave numerical solver without requiring separable coordinates. The method is benchmarked against the analytical Mie–Minkowski solution for a rotating circular cylinder, showing quantitative agreement in both intensity and phase. We further examine photonic-hook formation under Gaussian and Bessel illumination and show that geometry, rotation rate, and beam structure jointly modify the hook trajectory and focusing characteristics. The proposed method provides a numerical route for studying rotation-induced near-field redistribution in non-canonical cylindrical scatterers. It may support the design of rotation-sensitive optical manipulation and sensing configurations Текстовый файл AM_Agreement |
