Analogies between light optics and charged-particle optics
Sameen Ahmed Khan
The close analogy between geometrical optics and the classical theories of charged-particle beam optics have been known for a very long time. In recent years, quantum theories of c…
Wavelength-Dependent Effects in Maxwell Optics
Sameen Ahmed Khan
We present a new formalism for light beam optics starting with an exact eight-dimensional matrix representation of the Maxwell equations. The Foldy-Wouthuysen iterative diagonaliza…
Foldy-Wouthuysen transformation and a quasiparaxial approximation scheme for the scalar wave theory of light beams
Sameen Ahmed Khan, Ramaswamy Jagannathan, Rajiah Simon
The Foldy-Wouthuysen iterative diagonalization technique is applied to the Helmholtz equation to obtain a Hamiltonian description of the propagation of a monochromatic quasiparaxia…
Maxwell Optics: III. Applications
Sameen Ahmed Khan
A new formalism of beam-optics and polarization has been recently presented, based on an exact matrix representation of the Maxwell equations. This is described in Part-I and Part-…
Maxwell Optics: II. An Exact Formalism
Sameen Ahmed Khan
We present a formalism for light optics starting with the Maxwell equations and casting them into an exact matrix form taking into account the spatial and temporal variations of th…
