| Resumo: | In this work, we deal with the analysis of transmittance, reflectance, and absorption spectra
of light in cylindrical quasiperiodic structures with and without graphene. In chapter one
we introduce some remarkable developments in photonic crystals, semiconductors, and we
discuss about the concept of quasicrystals. In chapter two, we make a review of Fibonacci,
Octonacci, Double–Period and Thue–Morse sequences, and we describe how the concept
of quasiperiodic crystals arose mainly due to Dan Shechtman’s work. We also review
graphene’s main properties and we finish the chapter by showing relevant works in the field
of light propagation through cylindrical photonic crystals. In chapter three we develop
a general transfer-matrix method in cylindrical geometry by using Maxwell’s equations.
Afterwards, in chapter four we use the mathematical model described in earlier chapter
and we make the analysis of transmittance, reflectance, and absorption spectra for both TE
and TM modes, with embedded graphene at the interfaces and without graphene. Finally,
in the last chapter, we make some conclusions about the results of the Cylindrical Photonic
Quasiperiodic Crystals, analyzing possible applications and perspectives of further studies
on this topic. |
