We are pleased to announce the first session in our student seminar series 2017. Two of our students will be presenting on  WednesdayMarch 15 from 12:00 pm – 1:00 pm in ICE 8-207. 

Seminar #1: Haitham Abu Damis – “Wearable and On-body Antennas for Biomedical Applications


 

Abstract

Square-loop antennas for wearable applications in the 2.45 GHz (ISM) region are presented and compared. Both antennas were simulated, and then printed on flexible DuPont Kapton sheets for measurements. The standard square-loop antenna was modified by adding four circular patches to its sides in an effort to enhance performance. The new antenna is called the Quadruple Loop (QL) antenna. Simulations and measurement results show that the QL antenna demonstrated robust operation over a wider impedance bandwidth compared to that of the standard square loop antenna.

Biography

Haitham graduated from the Canadian University of Dubai (CUD) with a B.Sc. in telecommunications engineering. Throughout 2009-2013, he has worked with field programmable arrays (FPGA) and wireless sensor networks (WSN). As of 2014, he has been working on the development of body-worn antennas as part of his M.Sc. degree requirements.

Seminar #2: Rezvan Rafiee Alavi – “RWG MoM-via-Locally Corrected Nystrom Method for Source Reconstruction of Planar Very-Near-Field Measurement and Its Acceleration Using Multi-Level Fast Multipole Method


 

Abstract

Locally Corrected Nyström (LCN) method is used to solve magnetic field integral equations (MFIE) of the equivalent current method (ECM) in the planar very near-field measurement of antennas and RF circuits. The exact relationship between Rao-Wilton-Glisson (RWG) method of moments (MoM) and first-order, and zero-order LCN is established for both magnetic and electric currents to ensure normal current continuity between adjacent triangular patches. The proposed method is a point-based RWG discretization of MFIE and causes a noticeable decrease in the degree of freedom. It consequently eliminates spurious charges and significantly lowers the condition number of the impedance matrix. Moreover, it is more efficient to be accelerated by fast algorithms such as multi-level fast multipole method (MLFMM).

Biography

Rezvan Rafiee received the B.S. degree from the University of Tehran in 2009, in electrical engineering, and M.S. degree from Iran University of Science and Technology, in 2013, in Telecommunication, Fields, and Waves. Currently, she is a Ph.D. student at University of Alberta, where she has been since May 2014. Her research interests include Antenna and Propagation, Passive and Active Microwave Circuits, Numerical Methods in Electromagnetics, Inverse Electromagnetic Scattering, and Remote Sensing, and Microwave Measurements.

The IEEE Northern Canada Section Antennas & Propagation Society and the Microwave Theory & Techniques Society (IEEE NCS APS/MTTS) joint chapter is pleased to announce that we will be hosting a technical seminar by Rogers Corporation sales engineer Paul Jamiel.  Mr Jamiel will be presenting on the characterization of dielectric constants of various Rogers materials.

Where:

MEC 4-1, University of Alberta

When:

13-Sep-2016 12:00PM to 1:00PM

 Abstract

One of the key properties of PCB laminates is dielectric constant or Dk. The purpose of the presentation is to provide a basic overview of some common Dk test methods, define Process Dk and Design Dk and using Rogers Microwave Impedance Calculator to determine Design Dk.

Biography

Paul has 38 years of experience in the Printed Circuit Board industry with nearly half of those years spent manufacturing bare boards and the rest in manufacturing and selling copper clad materials.  In his current role as Sales Engineer for the NW U.S and Western Canada, Paul provides support for PCB Fabricators and guidance to PCB Designers on material selection, material stack-up considerations, and design for manufacturability.

The IEEE Northern Canada Section Antennas & Propagation Society and the Microwave Theory & Techniques Society (IEEE NCS APS/MTTS) joint chapter is pleased to announce that we will be hosting a seminar by Distinguished Microwave Lecturer, Dr. Madhu S. Gupta from the University of California, San Diego. Dr. Gupta be giving a presentation titled “Microwave Engineering: What is it, Where is it Headed, and How Does it Serve Mankind.

Where:

ETLC 1-013, University of Alberta

When:

17-May-2016 1:15PM to 2:30PM

Abstract

  • What is Microwave Engineering: how it is different from low-frequency or optical engineering; what are its theoretical underpinnings; to what applications is microwave engineering put, and what makes microwaves particularly suitable, or even unique, in those applications; why is it necessary to study RF and microwave theory even if all you want to do is “just design circuits”.
  • What are the Frontiers of the Field: what is the present state-of-the-art in this field, and the challenges for the future; what technological developments and newer applications are driving the future evolution of the field; what are some of the open research problems; how is the practice of microwave engineering likely to change in coming decades.
  • How does it Contribute to Quality of Life: how microwave engineering meets the human needs of communication, safety and security, decontamination and environmental remediation, health and biomedical applications, agriculture and food treatment; material processing; power generation and transmission; space exploration; material processing; and the generation, transport, and efficient utilization of electrical energy.

Biography

Madhu S. Gupta received the Ph.D. degree in Electrical Engineering from the University of Michigan, Ann Arbor, and is presently both an Adjunct Professor of Electrical & Computer Engineering at University of California, San Diego and the RF Communications Systems Industry Chair Professor at San Diego State University.  Along with his other technical interests, his work concerns noise and fluctuations in devices that are active, nonlinear, very small, or used in high-speed/high-frequency applications.  Dr. Gupta is an IEEE Fellow; has served as the Editor of IEEE Microwave and Guided Wave Letters and IEEE Microwave Magazine and of three IEEE Press books; has been a conference organizer and Chair of the Technical Program Committee of IMS2010; and was the President of the IEEE Microwave Theory & Techniques Society in 2013.  He has received the 2008 Distinguished Microwave Educator Award from IEEE MTT Society, in addition to a number of awards for outstanding teaching.  He also firmly believes that every technical talk should be entertaining, enlightening, and inspiring.

Their work in the development of the sensor has sparked an interest in this respective discipline and they are all intending to further pursue the development of sensing devices.

Seminar #2: Mohammad Zarifi – “Microwave Planar Resonator Sensors for Nano-scale Phenomena Detection


Mohammad MohammadQR

Abstract

Microwave planar resonators are emerging as cheap, compact, label-free and highly sensitive detection and quantification devices. These devices are particularly favored for sensing purpose due to their geometry, electromagnetic field enhancements in the coupling gap and compatibility with established printed circuit board manufacturing. However, the lack of selectivity and resolution in what is essentially a permittivity-sensing method are impediments to wider adoption and implementation of this sensing platform. This work is presenting selectivity and sensitivity engineered microwave sensor by employing Micro and Nano-scale materials. UV-sensitive titanium dioxide nanotubes are used to enhance the sensitivity and selectivity in our approach, which demonstrate promising results in gas sensing and light-intensity detection applications.
