Progress on investigation of nonlinear propagation of electromagnetic pulse in metamaterials

摘要

Metamaterials (MMs) are artificial structures, which can be engineered to satisfy the prescribed requirements. The most important difference between an ordinary medium and a MM is that the former has a constant permeability, while the latter has a dispersive and controllable permeability. MMs can extend the electromagnetic properties of conventional materials, and the study of the nonlinear propagation of ultrashort pulses in MMs could lead to completely new electronic and optical devices. In this paper, the research advances on the propagation of electromagnetic pulses in MMs with third-order nonlinear response are briefly described. Special effort is focused on the typical nonlinear optical phenomena such as modulation instability, bright and dark solitons.
