    "abstract": "The Classification of Polarization elements, the polarization affecting\noptical devices which have a Jones matrix representation, according to the\ntypes of eigenvectors they possess, is given a new visit through the\nGroup-theoretical connection of polarization elements. The diattenuators and\nretarders are recognized as the elements corresponding to boosts and rotations\nrespectively. The structure of homogeneous elements other than diattenuators\nand retarders are identified by giving the quaternion corresponding to these\nelements. The set of degenerate polarization elements is identified with the so\ncalled `null\u0027 elements of the Lorentz Group. Singular polarization elements are\nexamined in their more illustrative Mueller matrix representation and finally\nthe eigenstructure of a special class of singular Mueller matrices is studied.",
