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…
On the form of Lorentz-Stern-Gerlach force
Sameen Ahmed Khan, Modesto Pusterla
In recent times there has been a renewed interest in the force experienced by a charged-particle with anomalous magnetic moment in the presence of external fields. In this paper we…
