We are pleased to announce the third speaker for our Student Seminar Series, Mohammad Zarifi, who will be presenting a talk titled “Microwave Planar Resonators for Sensing Applications”.  Come and meet local researchers  in the microwave community and learn about the latest developments in this area.  Free pizza and refreshments will be available.

Abstract
Microwave resonators have been around for more than decades and been widely studied for mobile and satellite communications, radar, and electronic warfare applications. Recently they demonstrate a huge potential to be used as non-contact sensors in remote sensing fashion. These resonators are low cost, easy to implement and have a long life time, and their ability to perform in non-contact sensing mode, makes them attractive for harsh or ultra clean areas that sensor contact may reduce the sensor’s life time or contaminate the target sample. In this presentation, we will demonstrate the potential of these types of sensors in different areas from liquid interface detection to gas sensing.


We are still accepting applicants for future seminar series. To become one of our student presenters please send an email our Student Liaison Officer, Souren Shamsinejad, at s.s@ualberta.ca  with your topic.

Abstract
The optimization of radio frequency coil arrays for optimal Magnetic Resonance Imaging (MRI) and the mitigation of coupling between elements are presented. Coupling affects the optimum preamplifier noise matching, can cause resonant frequency splitting and degrade individual coil sensitivities. A theoretical framework for modeling capacitive coupling is shown as well as the benefits of using naturally decoupled orthogonal coils, taking account of preamplifier and electronic circuitry noise.

We are pleased to announce our first speaker for our Student Seminar Series, Ward Newman, who will be presenting a talk titled “First demonstration of outcoupling spontaneous emission from hyperbolic metamaterials using a plasmonic nano antenna”.  Come and meet local researchers  in the microwave community and learn about the latest developments in this area. Free pizza and refreshments will be available.

Abstract:
Directional light extraction of plasmonic modes in a hyperbolic metamaterials (HMMs) is demonstrated by direct coupling of resonance cones from Quantum Dots (QDs) underneath a HMM using a high index bulls-eye grating antenna. Theoretical and experimental details of hyperbolic metamaterials, plasmonic antennas and quantum dots are presented with a focus on drawing analogies between the optics and microwave research communities.

Call for Presentations for Student Seminar Series held by IEEE Northern Canada AP/MTT Jt. Chapter:

Dear Undergraduate/Graduate students,

 

The IEEE Northern Canada Section AP-S/MTT-S joint chapter is looking for students who are interested in presenting their research or capstone projects in student talks held at the University of Alberta. Presenters will be awarded based on audiences' evaluations.

If your field of study is related to Electromagnetics, Microwaves, or Antennas, we would like to invite you to present your work in one our seminars. In addition to providing a valuable speaking experience and resume enhancement, this opportunity can provide you with publicity and peer feedback of your work.

We would appreciate your forwarding our invitation email to your group as well.

The first seminar will be held on January 29 and the rest repeat every other Wednesday until April 9.

If you are interested in signing up or have any questions, please contact our Student Liaison Officer, Souren Shamsinejad, at s.s@ualberta.ca.

 

Regards,

The IEEE Northern Canada AP /MTT Jt. Chapter

Dr. F. M. Ghannouchi
Abstract
Data traffic and wireless applications have experienced exponential growth; and, in order to cope with the demand for higher capacity, the numbers of base stations and networks are increasing rapidly. This increase raises several cost and environmentally related challenges for wireless network infrastructure providers and operators, as well safety related concerns for users and government regulators. In order to reduce operating costs and minimize the carbon dioxide (CO2) emission footprint of communication networks, many wireless infrastructure providers and operators have been highly active in investigating new approaches and techniques to reduce energy consumption of base stations, mobile terminals and communication networks with the aim of implementing and deploying power-efficient “green” radio architectures and smart-grid wireless communication networks. This talk will highlight the why it important to reduce power consumption of communications network and how we can achieve it by adopting a holistic and  end-to-end-comprehensive approach, crossing the different layers of the Open System Interconnection (OSI) model.

A Class of Printed Leaky Wave Antennas
Microwave and millimeter wave antennas are vital components for wireless and satellite communications, radars and other sensors, and many other emerging applications. The presentation will start by introducing some  research activities at the Royal Military College of Canada that address recent and emerging research directions in the field. This will be followed by describing   a new class of one and two dimensional printed leaky wave antennas..

 Leaky wave antennas form one type of traveling wave antennas in which an aperture is illuminated by the fields of a traveling wave.  Usually a leaky wave stems from a close guiding structure that supports traveling waves but has some means of continuous power leakage into the exterior region.  The illuminated aperture extends over several wavelengths and is limited by wave attenuation caused by power leakage. 
The basic properties of leaky wave antennas were founded in the pioneering work of Tamir and Oliner back in the early 1960s and later in the work of Jackson and Oliner.  Recently, the need for high gain printed antennas has revived interest in leaky waves resulting in a great number of papers on printed leaky wave antennas. . In here we discuss leaky waves analytical properties and their supporting structures. A new coplanar surface wave- based launcher feed  system  for direct excitation of leaky waves is described.. Various high gain planar antenna configurations with  partially reflecting screens  will be studied in detail as  examples of new scanning leaky wave antenna structures. .  Analysis of some of these structures reveals the main properties of leaky wave antennas and provides some physical insight into their nature and future potential developments.  In addition, and based  on the unique properties of the newly developed surface wave  launchers, a new way of designing associated microwave guiding structures for integration with antennas or for use  on their own in microwave circuits is presented:
