Theoretical analysis reveals zero backscatter and directional polarization effects in magnetic spheres, highlighting novel optical conditions for small particles.

Key Points

To describe novel electromagnetic scattering and polarization phenomena produced by magnetic spheres under specific permittivity and permeability conditions.
Analytically evaluated electromagnetic wave scattering formulations for magnetic spheres.
Examined boundary behavior in the small-particle (long-wavelength) limit across relative permittivity (∊) and permeability (μ) relationships, focusing on ∊ = μ and the refractive index condition m = 1 (μ = 1/∊).
Demonstrated that setting ∊ = μ completely eliminates backscatter gain while preserving the incident radiation's polarization state in scattered waves.
Identified conditions within the small-particle limit that produce zero forward scatter, complete polarization in non-forward directions, and forward-to-backscatter asymmetry, particularly when μ = 1/∊.
