Depolarization of circularly polarized light in the Mie resonance region

[摘要] We show that a disordered ensemble of dielectric particles near the Mie resonances has anomalous depolarizing properties. Under the first Kerker condition the depolarization length of circularly polarized light reaches its peak value, and can be ten times greater than the transport mean free path. The second Kerker condition is shown to be satisfied as the refractive index of particles increases. In this case, the depolarization length is minimum and almost coincides with the mean free path.
