ABSTRACT:

In this presentation, I will give an overview of the progress that has been made during the past decade in the area of electromagnetic and acoustic wavefield imaging by researchers in the Electromagnetic Imaging Laboratory (EIL) in the Department of Electrical and Computer Engineering at the University of Manitoba. The talk, as well as the research area, divides naturally into a discussion of inverse problems, inversion algorithms, experimental systems, and imaging applications. In the area of inverse problems I will overview the various electromagnetic and ultrasonic mathematical formulations available and discuss the general issue of their ill-posedness. I will then discuss some of the algorithms the EIL has been working on for the solution of these problems. This includes the concept of multimodal microwave/ultrasonic (MW/US) imaging: the choices available on the fusion of quantitative and qualitative algorithms. I will then turn to the experimental systems we’ve built to verify our research and the progress being made on the commercialization of a system for the imaging of stored grain. I will discuss the use of multimodal MW/US imaging for breast imaging and the plans we have on developing systems for this application.

Abstract of the Presentation:

From frequency selective surfaces (FSS) to electromagnetic band-gap (EBG) ground planes, from impedance boundaries to Huygens metasurfaces, novel electromagnetic surfaces have been emerging in both microwaves and optics. Many intriguing phenomena occur on these surfaces, and novel devices and applications have been proposed accordingly, which have created an exciting paradigm in electromagnetics, so called “surface electromagnetics”. This seminar will review the development of electromagnetic surfaces, as well as the state-of-the art concepts and designs.

Abstract of the Presentation: As computational methods for solving Maxwell’s equations become mature, the time has come to tackle much more challenging multiphysics problems, which have a great range of applications in sciences and technologies. In this presentation, we will use four examples to illustrate the nature and modeling of multiphysics problems. The first example concerns the heat problem in integrated circuits due to electromagnetic dissipated power, which requires an electrical-thermal co-simulation. The second example considers modeling of monolithic microwave integrated circuits, which consist of both distributive and lumped circuit components. The third is the simulation of vacuum electronic devices using the particle-in-cell method, which solves Maxwell’s equations and particle kinetic equation, and the fourth example simulates the air and dielectric breakdown in high-power microwave devices by coupling electromagnetic modeling with various plasma models. With these examples, we will discuss the methodologies and some of the challenges and potential solutions in multiphysics modeling.

Waves Chapter Seminar – LTE on Unlicensed Band – February 22, 2017

Saturday, February 11th, 2017

IEEE Winnipeg Waves Chapter (APS/MTTS/VTS) is pleased to present:

=================================================================

Seminar Title: LTE on Unlicensed Band

Abstract of the Presentation: Future 5G cellular networks are facing the challenging task on increasing their capacity dramatically. Despite some cutting-edge capacity-approaching techniques, the limited licensed spectrum is still a major bottleneck for capacity improvement. To tackle this issue, a new standard has been developed within 3GPP for LTE systems, currently on the licensed bands, to operate on the unlicensed bands, which is called LTE on unlicensed bands (LTE-U). LTE has many advanced techniques, which can be exploited in the unlicensed bands to achieve a high spectral efficiency. However, the unlicensed bands are currently occupied by the widely-deployed WiFi networks.  The major challenge on LTE-U is how to design fair and efficient coexistence mechanisms between LTE and WiFi networks. In this talk, we will first discuss traditional traffic offloading, resource sharing, and hybrid of the both for LTE users to optimally exploit unlicensed bands while guaranteeing of the QoS of the existing WiFi users. To improve both the LTE and WiFi users simultaneously and achieve a win-win situation, we then provide a novel traffic offloading strategy, which is just opposite to the traditional one and offloads some WiFi users to the LTE networks and at the same time relinquishes some unlicensed bands to LTE-U. Since the unlicensed bands are usually operated less energy-efficiently than the licensed ones due to the higher carrier frequency of the unlicensed bands and larger pass-loss, we also present a framework for energy-efficiency (EE) optimization in LTE-U. We establish a criterion to determine whether the EE of the LTE system can be improved with the help of the unlicensed bands. Based on the criterion, we then develop a joint licensed and unlicensed resource allocation algorithm to maximize the EE of each LTE small cell base station.
