中文摘要：

我们基于异种组织由单人赛否定的介电常数和单人赛否定的渗透媒介组成的 photonic 学习了多重隧道的过滤器。结果证明在 zero-ϕ_{异质的接口 M 的数字增加的 eff} 差距增加。在 zero-ϕ_eff 差距等于异质的接口 M 的，并且它能被用作 M 隧道过滤器。这结果提供一个可行方法调整多重隧道的过滤器的隧道数字。当损失被包含时，结果证明回声模式的电场主要随异质的接口和抑制因素的数字的增加腐烂。而且，在多重隧道的过滤器的优秀因素和异质的接口 M 的数字之间的关系是线性的，并且多重隧道的过滤器的优秀因素随抑制因素的增加减少。这些结果提供可行方法调整多重隧道的过滤器的优秀因素。

英文摘要：

We studied the multiple-channel filters based on photonic heterostructures consisting of single-negative permittivity and single-negative permeability media. The results showed that the number of resonance modes inside the zero-φeff gap increases as the number of heterogenous interface M increases. The number of resonance modes inside the zero-φeff, gap is equal to that of heterogenous interface M, and it can be used as M channels filter. This result provides a feasible method to adjust the channel number of multiple-channel filters. When losses are involved, the results showed that the electric fields of the resonance modes decay largely with the increase of the number of heterogenous interface and damping factors. Besides, the relationship between the quality factor of multiple-channel filters and the number of heterogenous interface M is linear, and the quality factor of multiple-channel filters decreases with the increase of the damping factor. These results provide feasible methods to adjust the quality factor of multiple-channel filters.
