Metamaterials are artificially engineered devices that go beyond the properties of
conventional materials in nature. Metamaterials allow for the creation of negative refractive …

Recently, there has been an increased interest in exploring periodic structures with higher
symmetry due to various possibilities of utilizing them in novel electromagnetic applications …

We propose a circular twist-symmetric dielectric waveguide that is polarization-selective. In
the practical implementation of optical fibers, a selective circular polarization is more …

This paper presents a full electromagnetic (EM) characterization of metallic lenses. The
method is based on the utilization of free-space transmission and reflection coefficients to …

In this thesis, periodic structures with higher symmetries symmetries are discussed. The
main focus of the thesis is on twist symmetries. Importantly, the attractive properties of twist …

This thesis focuses on the understanding and computation of the dispersion properties of
periodic structures possessing higher symmetries with the multimodal transfer matrix method …

The Multimodal Transfer Matrix Method (MMTMM) is a hybrid approach that efficiently
computes the dispersion relation of a periodic structure. It is able to retrieve both the phase …

The Multimodal Transfer Matrix Method (MMTMM) is a hybrid method to compute the
propagation constants of periodic structures that combines in-house/commercial software …

Here, we study the propagation of a twist-symmetric dielectric rod with three different
methods: eigenmode solver, multimode Bloch analysis, and scattering parameters of a …
