Within the framework of Maxwell's equation we have studied light propagation through a finite heterostructure composed of a pair of bilayers with metamaterial/nonlinear Kerr slabs, with the inclusion of an air defect layer between them. The defect layer gives rise to modes, within the plasmon polariton gap, which are the subject of the present investigation. In this way, the number of modes, their intensities and frequency positions are obtained as functions of layer width, as well as of nonlinearity strength. We have found that this simple structure offers a wide variety of possibilities in the control of light, by optimal combinations of nonlinear strength with defect layer width.

在麦克斯韦方程组的框架内，我们研究了通过有限的异质结构的光传播，该结构由一对双层组成，这些双层具有超材料/非线性Kerr平板，并且在它们之间包括一个空气缺陷层。缺陷层在等离激元极化子间隙内引起了模式，这是本研究的主题。以此方式，获得模数，其强度和频率位置作为层宽度以及非线性强度的函数。我们已经发现，这种简单的结构通过非线性强度与缺陷层宽度的最佳组合，为光的控制提供了多种可能性。
