Non-Rayleigh scattering behavior for anisotropic Rayleigh particles
Derived from the light scattering by a radially anisotropic sphere, unusual scattering behavior is exhibited, which breaks the Rayleigh law (scattering efficiency 𝑄sca∼𝑞⁴ as 𝑞→0, where 𝑞 is the size parameter). Under certain conditions, we demonstrate an asymptotical relation between 𝑄sca and 𝑞, i.e., 𝑄sca=𝐹𝑞⁸, 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]
