Electromagnetic wave propagation inside a material medium: an effective geometry interpretation [PDF]

, 2001
We present a method developed to deal with electromagnetic wave propagation inside a material medium that reacts, in general, non-linearly to the field strength.

The pseudo-limit problem existing in electromagnetic radiation transmission and its mathematical physics principle analysis

Open Physics, 2019
In the study of electromagnetic radiation transmission for large airflow layers, it is found that not all electromagnetic waves are capable of forming waveguide propagation, and have a limit value problem.

Propagation of transient electromagnetic waves in time-varying media-direct and inverse scattering problems [PDF]

Inverse Problems, 1995
Summary: Wave propagation of transient electromagnetic waves in time-varying media is considered. The medium, which is assumed to be inhomogeneous and dispersive, lacks invariance under some translations. The spatial variation of the medium is assumed to be in the depth coordinate, i.e. it is stratified.

Poles and zeros of the scattering matrix associated to defect modes

, 2000
We analyze electromagnetic waves propagation in one-dimensional periodic media with single or periodic defects. The study is made both from the point of view of the modes and of the diffraction problem.
