In 2019, we demonstrated that a local measurement of s0 and s3 at 90° provides access to the expected (integrated) value of electromagnetic helicity in the dipolar regime (see eq 8 in ref (1)). Later, in 2023, we discovered that the relationship between s0 and s3 and their integrated counterparts, ⟨s0⟩ and ⟨s3⟩, holds true for any scattering angle.^2^ Furthermore, we found that this relationship extends to larger spherical objects when excited with structured light, expanding its applicability beyond the dipolar regime.

However, it is important to acknowledge that the results of refs (1 and 2) cannot be used to solve Maxwell’s equations. To start with, the Stokes vector is not measured, making it impossible to disentangle the electric and magnetic scattering coefficients. In addition to this, the imposition of the lossless condition, which is crucial for solving Maxwell’s equations by linking the amplitude and phase of the scattering coefficients (see eq 11 of this work), is also absent in refs (1 and 2).
