   Abstract : The discovery of metamaterials has led to major advances in different fields of physics including optics, microwave engineering and acoustics. Specific to theoretical electromagnetism, the introduction of metamaterials have led to the development of negative-index materials (NIMs) with simultaneous negative permittivity and negative permeability with backward-wave propagation.

3. 2. Model of a Wave Diode in a Nonlinear System

   University essay from Linköpings universitet/Teoretisk Fysik; Linköpings universitet/Tekniska högskolan

   Author : Erik Johansson; [2014]
   Keywords : Discrete Nonlinear Schrödinger Wave Diode Cubic Saturable Asymmetric Propagation;

   Abstract : In this diploma work, two versions of the discrete nonlinear Schrödinger (DNLS) equation are used to model a nonlinear layered photonic crystal system; the cubic DNLS (cDNLS) equation and the saturable DNLS (sDNLS) equation. They both have site-dependent coefficients to break mirror symmetry with respect to propagation direction, as well as to describe the linear and nonlinear properties of the system. READ MORE
