Skyrmions through spatially varying depolarizers. The output Stokes field of a first-order Néel-type Skyrmion after passing through a type-I depolarizing media with spatially varying parameters d1, d2, d3 and ε = 1. Note from equation (31) that the output Stokes field is independent of the incident degree of polarization. This figure therefore does not include the distribution of P. The Skyrmion numbers are computed using a central difference for partial derivatives and the ‘nquad’ function from SciPy for integration
