We study one- and two-dimensional transmission of electromagnetic waves through a finite slab of a dielectric material with negative refraction. In the case when the dielectric slab possesses an intensitydependent nonlinear response, we observe the nonlinearity-induced wave transmission through an opaque slab accompanied by the generation of spatiotemporal solitons. We solve this problem numerically, by employing the finite-difference time-domain simulations, for the parameters of microstructured materials with the negative refractive index in the microwave region, but our results can be useful for a design of nonlinear metamaterials with the left-handed properties in other frequency range.
我们研究了电磁波在具有负折射特性的有限厚度电介质平板中的一维和二维传输。当电介质平板具有强度依赖的非线性响应时，我们观察到非线性诱导的波通过不透明平板的传输，并伴随着时空孤子的产生。我们通过有限差分时域模拟对该问题进行了数值求解，所针对的是微波区域具有负折射率的微结构材料参数，但我们的结果对于设计其他频率范围内具有左手特性的非线性超材料可能是有用的。
