AbstractThe knowledge of complex properties of dielectric materials is of key importance for the design of microwave and millimeter-wave components, as well as other research areas such as material science and biological research. On the area of RF/Microwave research, the dielectric measurement of both electrical and magnetic properties of materials proves to be of upmost importance, specially in the development of novel components such as, printed circuits substrates, antenna lenses and absorbers, to name a few.  There are several well-known techniques and methods for the measurement of complex permittivity and permeability.

TitleWireless Over Fiber Systems Based on 1.55 µm Directly Modulated VCSELs
AbstractRadio-over-fiber technology, used in the transport of radio signals over optical fiber by means of an optical carrier between a remote site and a central node of a cellular network, is an attractive solution for backhauling of a large number of remote antennas, enabling the shifting of the hardware complexity from base stations to a central station. Integration of both optical and wireless broadband infrastructures into the same backhaul network leads to significant simplification and cost reduction of base stations permitting equipment sharing and dynamic allocation of resources, which in turn leads to simplified system operation and maintenance. Wireless systems on the other hand are evolving rapidly and new standards are appearing, such as the Long-Term Evolution aiming at satisfying the required need for increasing bandwidth. Radio-over-fiber systems are known to be susceptible to noise and non-linear distortion in particular to the large peak-to-average power ratio of orthogonal frequency division multiplexing signals employed in these standards. In this work we compare, experimentally and through simulation, the performance of orthogonal frequency division multiplexing and single carrier frequency division multiple access signals, in radio-over-fiber applications, using directly modulated VCSELs.

TitleMachine Learning for Big Data Processing
AbstractMachine Learning (ML) is a subfield of artificial intelligence that is concerned with the design, analysis, implementation, and applications of programs that learn from examples or experience. Learning from data is commercially and scientifically important. ML consists of methods and respective software that extract automatically interesting knowledge (patterns, models, relationships) in large databases of sometimes chaotic and redundant information. ML is a data-based knowledge-discovering process that has the potential not only to analyze events in retrospect but also to predict future events or important alterations. The objective of this lecture is to introduce the PhD students to the research area of ML. The lecture will give a flavor of Supervised (classification and regression) versus Unsupervised (clustering) learning paradigms. Distance (similarity) measures, instance based classifiers, Bayesian statistical learning, and performance evaluation (confusion matrix). ML applications, such as text mining, image classification, brain data processing will be discussed.

TitleNonlinearity in Wireless Communication Systems
AbstractDespite the many studies that have been undertaken to understand nonlinearity in wireless communication systems, most undergraduate electrical engineering programs are still confined to linear analysis and design tools, hiding the significant advances we have been witnessing in the recent years.  So, this seminar will reveal the ubiquitous presence of nonlinearity in all wireless communication circuits and the recent efforts made to understand, model, predict, and measure its diverse manifestations. We aim to bring telecommunications engineers’ attention to newly available techniques, and attract young researchers to pursue PhD studies on this scientifically exciting topic. Starting with some elementary properties of nonlinear systems (like nonlinear signal distortion, harmonic generation, frequency conversion and spectral regrowth), we will show that nonlinearity is present in all wireless circuits, either to perform a desired signal operation or as unintentional distortion. This way, we will show how wireless communications could not exist without nonlinearity, while we still struggle to get rid of its distortion effects. After this overview, we will introduce some recent advancements in nonlinear wireless circuit analysis tools and illustrate different types of models that are currently being used to represent and predict device, circuit, and system performance. Finally, we will focus the seminar on the newly developed lab instruments and their ability to assess device performance.
