(a) Normalized FID for TEM 00 ( x ′ ) mode focused laser beam ( w 0 = 2 λ ) in x ′ O ′ y ′ plane. Normalized FIDs in x ′ O ′ z ′ plane for chiral sphere ( k 0 r 0 = 3 π , ε r = 4 , μ r = 1 , κ = 0.5 ) illuminated by the above focused laser beam respectively with (b) ( x ′ 0 = y ′ 0 = z ′ 0 = 0 ) and (c) ( x ′ 0 = 2 λ , y ′ 0 = z ′ 0 = 0 ).
