Unitary and non-unitary operations on the Poincaré sphere and Pancharatnam-Berry phase with $\mathbf{Z}$ matrices

M. A. Kuntman, A. Kuntman, E. Kuntman

In polarization optics unitary and non-unitary operations can be carried out by the Jones matrix. $\mathbf{Z}$ matrix is the $4\times 4$ analogue of the Jones matrix and the Muelle…
