Self-focusing and envelope pulse generation in nonlinear magnetic metamaterials.

چکیده
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.

Gap solitons in metamaterials
Electromagnetic localization and existence of gap solitons in nonlinear metamaterials, which exhibit a stop band in their linear spectral response, is theoretically investigated. For a self-focusing Kerr nonlinearity, the equation for the electric field envelope with carrier frequency in the stop band where the magnetic permeability μ(ω) is positive and the dielectric permittivity ǫ(ω) is negat...
متن کاملStudy of non-linear interaction of circular laser pulse propagating through hot magnetized plasma in the presence of a planar magnetostatic wiggler
In this paper, the self-focusing property of an intense circularly polarized laser pulse in hot magnetized plasma is investigated theoretically. First, an envelope equation governing the spot-size of the laser beam for both left- and right-hand polarizations has been derived in the presence of a planar wiggler. Furthermore, non-linear dispersion relation of laser pulse is obtained by using Maxw...

Extensive studies of microwave properties of composite metallic structures led to the experimental demonstration of left-handed metamaterials [1] suggested long time ago [2]. Such metamaterials are created by resonant magnetic elements and operate for the wavelengths much larger than the period, allowing for the macroscopic effective medium description. The parameters of the effective medium de...
متن کاملSelf-focusing in air with phase-stabilized few-cycle light pulses.
We investigate the nonlinear optical phenomenon of self-focusing in air with phase-stabilized few-cycle light pulses. This investigation looks at the role of the carrier-envelope phase by observing a filament in air, a nonlinear phenomenon that can be utilized for few-cycle pulse compression [Appl. Phys. B79, 673 (2004)]. We were able to measure the critical power for self-focusing in air to be...
