The self-induced gap solitons in nonlinear magnetic metamaterials is investigated. It is shown that the self-induced gap solitons may exist due to the interaction of the discreteness and nonlinearity. The evolution of these localized structures is studied in the phase plane and analytical and numerical expressions are obtained.
研究了非线性磁性超材料中的自诱导带隙孤子。结果表明,由于离散性和非线性的相互作用,自诱导带隙孤子可能存在。在相平面中研究了这些局域结构的演化,并得到了解析表达式和数值表达式。
