Axion-Electromagnetic Waves [PDF]
Modern Physics Letters A, 2013 We extend the duality symmetry between the electric and the magnetic fields to the case in which an additional axion-like term is present, and we derive the set of Maxwell's equations that preserves this symmetry.

Fractional electromagnetic waves [PDF]
2011 11th International Conference on Laser and Fiber-Optical Networks Modeling (LFNM), 2011 In The present work we consider the electromagnetic wave equation in terms of the fractional derivative of the Caputo type. The order of the derivative being considered is 0<λ≤1. A new parameter σ is introduced which characterizes the existence of the fractional components in the system.
