[en] MICROWAVE DEVICES USING CARBON NANOTUBES AND GRAPHENE / [pt] DISPOSITIVOS DE MICROONDAS UTILIZANDO NANOTUBOS DE CARBONO E GRAFENO

GELZA DE MOURA BARBOSA 10 October 2014 (has links)
[pt] Esta Tese consiste na pesquisa, dimensionamento e desenvolvimento de estruturas de microondas que utilizam grafeno e nanotubos de carbono como componente fundamental. São apresentadas aplicações em dispositivos de micro-ondas e no domínio óptico, tais como filtros, conversores de frequência, antenas de microondas, absorvedores de microondas etc. Também são apresentados os resultados dos testes realizados em todos os dispositivos desenvolvidos. Alguns dispositivos contém inovações ainda não reportadas na literatura. / [en] This Thesis consists inthe research, dimensioning and design of microwave structures that use graphene and carbon nanotubes as fundamental component.
