Esta dissertação tem por objetivo desenvolver, a partir do estudo do problema canônico de espalhamento eletromagnético por um cilindro circular perfeitamente condutor, uma formulação assintótica uniforme para a difração por superfícies condutoras convexas. A solução obtida é então aplicada à análise de desempenho de refletores parabólicos com borda espessa visando fornecer subsídios ao projeto de antenas com nível de lobos secundários controlado.It is the purpose of this dissertation to develop an uniform asymptotic formulation for the diffraction by convex conducting surfaces, starting from the study of the canonical problem of electromagnetic scattering by perfectly conducting circular cylinders. The solution thus obtained in then applied...
