Periodic Integral Equation Formulation for the Numerical Analysis of Glide Structures

In this paper, we propose a technique based on integral equations, the periodic Green's function, and the method of moments discretization to analyze the dispersion diagram of non-canonical glide-symmetry unit cells. The technique is combined with a root finder approach to automatically identify the values of the wavevector that make the unit cell resonant. The proposed technique is tested on a glide fully metallic implementation of a Luneburg lens.
