Light propagation in quasiperiodic cylindrical systems with graphene

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...

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES Neste trabalho tratamos da análise dos espectros de transmitância, refletância e absorção de luz aplicados em estruturas cílindricas quaseperiódicas com e sem grafeno. No capítulo 1 introduziremos alguns feitos importantes no estudo de cristais fotônicos, na área de semicondutores e no conceito de quasicristais. No capítulo 2 faremos uma revisão das sequências de Fibonacci, Octonacci, Período–Duplo e Thue-Morse, e descreveremos como surgiu a ideia de cristais quasiperiódicos principalmente devido aos trabalho de Dan Shechtman. Além disso, revisamos as principais propriedades do grafeno e finalizamos o capítulo apresentando trabalhos relevantes na área de propagação de luz em cristais fotônicos cilíndricos. No capítulo 3 desenvolvemos o um método geral da matriz de transferência para a geometria cilíndrica a partir das equações de Maxwell, e dela podemos particularizar para os modos TE ou TM e escolher se colocamos ou não condutores, os quais obedecem à lei de Ohm. Depois, no capítulo 4 utilizamos os resultados matemáticos da matriz de transferência do capítulo anterior e fazemos uma análise dos espectros de transmitância, refletância e absorção para os modos TE e TM, bem como no caso com e sem grafeno. Por fim, no último capítulo faremos algumas conclusões sobre os resultados obtidos para os quasicristais fotônicos cilíndricos analisados, falaremos de algumas aplicações e mencionaremos algumas perpectivas nessa linha de pesquisa. 2022-10-06T19:55:06Z 2022-10-06T19:55:06Z 2022-08-16 masterThesis AMORIM, Jedson Fernandes de.
