1. Avaliação de desempenho de câmaras excitadas via linha de transmissão aplicáveis à compatibilidade eletromagnética. / Transmission line excited chamber performance evaluation applied to electromanetic compatibility.
This Thesis presents the proposition of a Transmission Line Excited Chamber configuration. This configuration is considered to be a potential solution for the constraints of reverberation chambers of nowadays. Among this constraints, e.g. the ones related to chamber operation at some MHz, is a physical restriction to implement in tests environments. Moreover

2. Estudo da convergência no método de elementos finitos aplicado a dispositivos eletromagnéticos não lineares. / Survey on the convergence of non-linear finite element method applied to electromagnetic devices in two-dimension.
This work presents a study on the convergence of non-linear finite analysis applied to the modeling of electromagnetic devices with plane symmetry. Three aspects have been thoroughly investigated which have influence on the convergence performance, namely: the relaxation factor in the Newton-Raphson algorithm, the model of the magnetization curve and the cho

3. DesG: uma nova metodologia para intervenção e coleta de dados magnetotelúricos / DesG: a new methodology for intervention and it collects of magnetotelluric data
This thesis presents two contributions to magnetotelluric data interpretation. The first one is a new MT inversion method, named Geologic-Descriptive Method (DesG) because it explicitly incorporates a priori information, keeping a close correspondence with the standard description of geological features. The user defines by means of geometric elements (point
