Shadrivov, Ilya V.Zharov, Alexander A.Zhorova, Nina A.Kivshar, Yuri S.2026-01-062026-01-06https://dspace-test.anu.edu.au/handle/1885/733761393We analyze nonlinear properties of microstructured materials with the negative refractive index, the so-called left-handed metamaterials. We demonstrate that the hysteresis-type dependence of the magnetic permeability on the field intensity allows changing the material properties from left-to right-handed and back. Using the finite-difference time-domain simulations, we study the wave reflection from a slab of nonlinear left-handed material, and observe the propagation of temporal solitons in such materials.4en200510.1109/IWAT.2005.146110433745009487
