In this paper, we present a general mode matching formulation to analyze the wave
propagation in glide-symmetric metallic surfaces drilled with periodic holes with an arbitrary …

We demonstrate the beneficial effects of introducing glide symmetry in a two-dimensional
periodic structure. Specifically, we investigate dielectric parallel plate waveguides …

A broadband planar microwave Luneburg lens made of a three-layer metasurface with
hexagonal symmetry is presented. This metasurface supports a transverse-electric mode …

The acoustic surface waves supported by hard surfaces patterned with repeat-period,
meandering grooves are explored. The single, continuous groove forms a glide-symmetric …

In this work we study planar metasurfaces comprised of two layers of hexagonal arrays of
circular metal patches. This two-layer geometry supports a bound surface wave that …

In this thesis, periodic structures with higher symmetries are studied. Their wave propagation
characteristics are investigated and their potential applications are discussed. Higher …

This paper introduces a new type of waveguide filter for multiple band antenna systems. The
proposed solution makes use of glide symmetric holey surfaces to provide the required …

In this work we present different planar metasurfaces, comprised of two or more layers.
These layers are stacked, with a very small separation, and displaced with respect to each …

The exploration of acoustic metasurfaces presented in this Thesis involves the
characterisation and verification through finite element method (FEM) modelling and …
