Self-focusing and envelope pulse generation in nonlinear magnetic metamaterials
arXiv:cond-mat/0612615 · doi:10.1103/PhysRevE.75.067601
Abstract
The self-modulation of waves propagating in nonlinear magnetic metamaterials is investigated. Considering the propagation of a modulated amplitude magnetic field in such a medium, we show that the self-modulation of the carrier wave leads to a spontaneous energy localization via the generation of localized envelope structures (envelope solitons), whose form and properties are discussed. These results are also supported by numerical calculations.
