Query: Weak measurement of elliptical dipole moments by C point splitting   We investigate points of circular polarization in the far field of
elliptically polarized dipoles and establish a relation between the angular
position and helicity of these C points and the dipole moment. In the case of
highly eccentric dipoles, the C points of opposite handedness exhibit only a
small angular separation and occur in the low intensity region of the emission
pattern. In this regard, we introduce an optical weak measurement approach that
utilizes the transverse electric (azimuthal) and transverse magnetic (radial)
far-field polarization basis. Projecting the far field onto a spatially varying
post-selected polarization state reveals the angular separation and the
helicity of the C points. We demonstrate the applicability of this approach and
determine the elliptical dipole moment of a particle sitting on an interface by
measuring the C points in its far field.
