    "abstract": "We present a formalism for light optics starting with the Maxwell equations\nand casting them into an exact matrix form taking into account the spatial and\ntemporal variations of the permittivity and permeability. This $8 \\times 8$\nmatrix representation is used to construct the optical Hamiltonian. This has a\nclose analogy with the algebraic structure of the Dirac equation, enabling the\nuse of the rich machinery of the Dirac electron theory. We get interesting\nwavelength-dependent contributions which can not be obtained in any of the\ntraditional approaches.",
