abstract = {In this paper, we study the wave propagation in a
metallic parallel-plate structure with glide-symmetric elliptical
holes. To perform this study, we derived a mode-matching
technique based on the generalized Floquet theorem for glide-symmetric structures. This mode-matching technique benefits
from a lower computational cost since it takes advantage of
the glide symmetry in the structure. It also provides physical
insight on the specific properties of Floquet modes propagating
in these specific structures. With our analysis, we demonstrate
that glide-symmetric structures with periodic elliptical holes
exhibit an anisotropic refractive index over a wide range of
frequencies. The equivalent refractive index can be controlled
by tuning the dimensions of the holes. Finally, by combining
the anisotropy related to the elliptical holes and transformation
optics, a Maxwell fish-eye lens with a 33.33% size compression
is designed. This lens operates in a wideband frequency range
from 2.5 GHz to 10 GHz.},
