Multimodal analysis of glide-symmetric dielectric/magnetic structures

In this contribution, we propose the use of the multimodal transfer matrix approach to investigate two-dimensional dielectric and magnetic periodic structures that possess glide symmetries. This method allows for the calculation of the attenuation constant in bandgaps, leaky structures, and material losses. In addition, this method enables a fundamental understanding of the operation of periodic structures. The method is also used to explain the differential response produced by dielectric/magnetic glide symmetries.
