Let us assume that a particle supports only electric and magnetic dipole modes with polarizabilities p = α α e E and m = ( μ μ μ μ 0 ) − − 1 α α m H (here we use the notation of magnetic polarizability in the manner of Bekshaev et al. rather than the notation of Nieto-Vesperinas et al.) expressed through the Mie coefficients as α α e = 4 π π ε ε 0 ⋅ ⋅ i 3 ε ε 2 k 3 a 1 , α α m = 4 π π μ μ 0 ⋅ ⋅ i 3 μ μ 2 k 3 b 1 . Then the cross sections are given by σ σ ext = σ σ ext (e) + σ σ ext (m) = 1 4 π π ε ε ε ε 0 ⋅ ⋅ 4 π π k ℑ ℑ ( α α e ) + 1 4 π π μ μ μ μ 0 ⋅ ⋅ 4 π π k ℑ ℑ ( α α m ) σ σ sc = σ σ sc (e) + σ σ sc (m) = 1 ( 4 π π ε ε ε ε 0 ) 2 ⋅ ⋅ 8 π π 3 k 4 | α α e | 2 + 1 ( 4 π π μ μ μ μ 0 ) 2 ⋅ ⋅ 8 π π 3 k 4 | α α m | 2 and, finally, the electric and magnetic absorption cross sections σ σ abs = σ σ abs (e) + σ σ abs (m) are σ σ abs (e) = 1 4 π π ε ε ε ε 0 ⋅ ⋅ 4 π π k [ ℑ ℑ ( α α e ) − − k 3 6 π π ε ε ε ε 0 | α α e | 2 ] and σ σ abs (m) = 1 4 π π μ μ μ μ 0 ⋅ ⋅ 4 π π k [ ℑ ℑ ( α α m ) − − k 3 6 π π μ μ μ μ 0 | α α m | 2 ]
