J. Gil, Phys. Rev. A 90, 043858 (2014)10.1103/PhysRevA.90.043858]. This fact is intimately linked to the existence of 3D polarization states with fluctuating directions of propagation, but whose associated polarization matrices R satisfy rank R=2. In this work, such peculiar states are analyzed and characterized, leading to a meaningful general classification and interpretation of 3D polarization states. Within this theoretical framework, the interrelations among the more significant polarization descriptors presented in the literature, as well as their respective physical interpretations, are studied and illustrated with examples, providing a better understanding of the structure of polarimetric purity of any kind of polarization state. 000075713 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E99$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2014-58303-P 000075713 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000075713 590__ $$a2.909$$b2017 000075713 591__ $$aOPTICS$$b23 / 94 = 0.245$$c2017$$dQ1$$eT1 000075713 591__ $$aPHYSICS, ATOMIC, MOLECULAR & CHEMICAL$$b12 / 36 = 0.333$$c2017$$dQ2$$eT2 000075713 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000075713 700__ $$aFriberg, Ari T. 000075713 700__ $$aSetälä, Tero 000075713 700__ $$aSan José, Ignacio 000075713 773__ $$g95, 5 (2017), 053856 [10 pp]$$pPhys. rev., A$$tPHYSICAL REVIEW A$$x2469-9926 000075713 8564_ $$s129277$$uhttps://zaguan.unizar.es/record/75713/files/texto_completo.pdf$$yVersión publicada 000075713 8564_ $$s110520$$uhttps://zaguan.unizar.es/record/75713/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000075713 909CO $$ooai:zaguan.unizar.es:75713$$particulos$$pdriver 000075713 951__ $$a2018-11-07-09:57:14 000075713 980__ $$aARTICLE
