Non-Rayleigh scattering behavior for anisotropic Rayleigh particles

Ni, Y. X.; Gao, L.; Miroshnichenko, A. E.; Qiu, C. W.

Description

Derived from the light scattering by a radially anisotropic sphere, unusual scattering behavior is exhibited, which breaks the Rayleigh law (scattering efficiency 𝑄scaβˆΌπ‘žβ΄ as π‘žβ†’0, where π‘ž is the size parameter). Under certain conditions, we demonstrate an asymptotical relation between 𝑄sca and π‘ž, i.e., 𝑄sca=πΉπ‘žβΈ, which is not realizable for isotropic particles in Rayleigh regime. Moreover, suitable adjustment of the anisotropic parameters can further suppress the coefficient 𝐹,...[Show more]
