研究了结合缺陷和多异质结构的杂化结构的传输特性。结果表明，通过调整缺陷的数量、位置和大小，可以大大扩大非传输频率范围，实现多通道滤波。在结构中考虑了一个、两个和三个通道滤波器。用传递矩阵法对实例进行了理论研究。
Transmission characteristics are studied for hybrid structures combining defects and multiple heterostructures. It is shown that the nontransmission frequency range can be substantially enlarged and the phenomenon of multiple-channeled filtering can be realized by adjusting the number, position, and size of the defects. One, two, and three channeled filters are considered in the structures. Examples are studied theoretically by transfer matrix methods.
