Abstract
A one-dimensional multilayer structure consisting of two symmetric parts with defect layers is designed, and properties of the multiple nonreciprocal transmission are investigated due to symmetrically distributed magneto-optic layers with opposite magnetic fields in composite structures. The transmission coefficient and energy band diagram of the system are obtained based on transfer matrix method. The numerical results show that there are three pairs of nonreciprocal dispersive curves with different modes in a certain bandgap. The influence of the thickness of defect layer and incident angle on nonreciprocal frequencies is also discussed. The multiple nonreciprocal transmission could in turn be potentially useful in optical isolators and optical resonators.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
