Single and three-phase grid-connected converters are widely used in energy conversion systems such as renewable energies systems, electrical vehicles, active filters, etc... Maintaining a good power quality level in modern electric grid remains the greatest challenge in front of the nonstop harmonic pollution generated by operating nonlinear systems. Traditionally, grid-connected converters are controlled with conventional vector control methods. However, several limitations are associated with these mechanisms especially in their applicability to dynamic systems. Advanced non-linear controllers were introduced also for this behalf. Several control techniques applied for the grid connectivity applications will be discussed. Recently, the mitigation towards intelligent-based controllers started to gain more and more attention and to be integrated in the control of the grid connected converters. On this behalf, an overview about the latest advances in this field will be discussed. Speaker(s): Dr. Fadia Sebaaly, Montreal, Quebec, Canada, Virtual: https://events.vtools.ieee.org/m/301714

Although unique potentials of terahertz waves for chemical identification, material characterization, biological sensing, and medical imaging have been recognized for quite a while, the relatively poor performance, higher costs, and bulky nature of current terahertz systems continue to impede their deployment in field settings. In this talk, I will describe some of our recent results on developing fundamentally new terahertz electronic/optoelectronic components and imaging/spectrometry architectures to mitigate performance limitations of existing terahertz systems. In specific, I will introduce new designs of high-performance photoconductive terahertz sources that utilize plasmonic nanoantennas to offer terahertz radiation at record-high power levels of several milliwatts – demonstrating more than three orders of magnitude increase compared to the state of the art. I will describe that the unique capabilities of these plasmonic nanoantennas can be further extended to develop terahertz detectors and heterodyne spectrometers with quantum-level detection sensitivities over a broad terahertz bandwidth at room temperatures, which has not been possible through existing technologies. To achieve this significant performance improvement, plasmonic antennas and device architectures are optimized for operation at telecommunication wavelengths, where very high power, narrow linewidth, wavelength tunable, compact and cost-effective optical sources are commercially available. Therefore, our results pave the way to compact and low-cost terahertz sources, detectors, and spectrometers that could offer numerous opportunities for e.g., medical imaging and diagnostics, atmospheric sensing, pharmaceutical quality control, and security screening systems. And finally, I will briefly highlight our research activities on development of new types of high-performance terahertz passive components (e.g., modulators, tunable filters, and beam deflectors) based on novel reconfigurable meta-films.

This presentation will begin with a general discussion on the current landscape of THz research and development. In particular, the state-of-the-art of MHz-through-THz material characterization will be briefly reviewed. Subsequently, two groups of free-space THz measurement techniques will be described for accurate material characterization and parametric extraction in connection with frequency independent optical paths. Quasi-optical mirror and lens systems are studied and developed over THz range to achieve precision complex permittivity measurements of dielectric substrates, films, and materials. To achieve a wide plane wave zone for the center of four-parabolic-mirror systems, two corrugated horns are designed and fabricated for the measurement systems. The Gaussicity of the corrugated horn is larger than 97.4%. For the proposed multiple reflection model and direct wave model, a set of closed-form expressions of loss tangent are derived from transmission parameters of the measurement systems. The resolution and uncertainty of loss tangent are examined according to the working frequency, the thickness of wafer or substrate, the real part of relative permittivity, and the transmission measurement uncertainty. The complex permittivity of Rogers/Duroid series PCB substrates, which are commonly used at microwave frequencies, and silicon wafers are measured over THz ranges.

CubeSat, a modular type of standardized modern small satellites, have been gaining steady popularity and attention from universities and space industries. In addition to education purpose, CubeSats have various promising applications as low-cost space exploration vehicles for technology demonstrations, multi-point observations of space environment, and monitoring/reporting proper deployment of expensive deep space instruments. Antennas are critical components for CubeSat missions. A CubeSat antenna may provide some or all of the following functions: telemetry, tracking, command (TT\&C), high speed downlink for payload data, receiving positioning data, and inter-satellite cross links. Most often, different antennas are required to keep the CubeSat assembly in modular fashion. On the other hand, antenna engineers strive to create solutions that could pack more functionality into one unit. This brings up a need to understand basics of CubeSat development cycle and link budget analysis, so that an electrical engineer would have sound knowledge of limiting factors (posed by the mechanical system and hardware of a CubeSat) to the antennas design. With rapid advancement of electronics, novel mechanical design, and aerospace technology, new progress in CubeSats is emerging every day. This calls for interests and early involvements of creative young minds. The objective of this presentation is to convey the basics of CubeSat development cycle, launch methods, typical CubeSat orbits, link budget analysis, various antenna solutions, and feasible classroom projects.

Conformal Integration of antennas with solar panels has wide applications, from small spacecraft, Mars rovers, to self-powered wireless sensors. It is particularly beneficial when the surface real estate is a major challenge, such as a CubeSat. A strategic integration not only reduces the development cost, promotes a robust communication link, but also increases the mission capacity by allowing more science instruments to be mounted on the CubeSat. This lecture covers different conformal antenna designs for solar panel integration, from UHF to Ka band. It includes antennas integrated under solar cells, around solar cells, and optically transparent antennas integrated on top of solar cells. It also covers low gain and high gain design. The high gain design mainly focuses on reflectarray antenna, which may be beneficial to those who wishes to study the subject. As these antennas are integrated with solar panel, a unique and complex subsystem, effects of solar cells on the antenna and vice versa need to be analyzed and quantified. The lecture presents analysis of a typical space-certified solar cell, extracted model, experimental set-up to quantify the interaction between solar cells and the integrated antennas.
