Cylindrically polarized modes (CPMs) of the electromagnetic field are very intriguing objects as they combine a complex polarization pattern with a complex spatial pattern. We investigate theoretical subtleties underlying their structure, in particular, a thorough theoretical description for spatio-polarization modes is developed. We show that two hybrid Poincaré spheres can be introduced to represent simultaneously the polarization and the spatial degrees of freedom of CPMs in accordance with conventional ways of displaying properties of optical beams, such as the Poincaré sphere for polarization. Possible mode-to-mode transformations accomplishable with the help of conventional polarization and spatial phase retarders are shown within this representation.
