Imaging with Electromagnetic Waves in Terminating Waveguides

Abstract. We study an inverse scattering problem for Maxwell’s equations in terminating waveguides, where localized reflectors are to be imaged using a remote array of sensors. The array probes the waveguide with waves and measures the scattered returns. The mathematical formulation of the inverse scattering problem is based on the electromagnetic Lippmann-Schwinger integral equation and an exp...

Analytic descriptions of cylindrical electromagnetic waves in a nonlinear medium

A simple but highly efficient approach for dealing with the problem of cylindrical electromagnetic waves propagation in a nonlinear medium is proposed based on an exact solution proposed recently. We derive an analytical explicit formula, which exhibiting rich interesting nonlinear effects, to describe the propagation of any amount of cylindrical electromagnetic waves in a nonlinear medium. The...

On Guided Electromagnetic Waves in Photonic Crystal Waveguides

This paper addresses the issue of existence and confinement of electromagnetic modes guided by linear defects in photonic crystals. Sufficient conditions are provided for the existence of such waves near a given spectral location. Confinement to the guide is achieved due to a photonic band gap in the bulk dielectric medium.

Cylindrical electromagnetic waves with radiation and absorption of energy

Cylindrical electromagnetic waves have been examined mostly with a radiation condition applied at the radial far field. In modern optical technology, there are however growing number of applications where both radiation and absorption of energy should be taken into account. In order to illustrate the ramifications of such energy balance, we take plasmonic waves propagating around a metallic nan...
