Dr. Mohammad S. Sharawi
Associate Professor
Electrical Engineering Department

Day/Time: Monday, August 11th, 2014, 11 AM
Location: The Royal Military College of Canada
Room: S4202 Sawyer Building

Abstract:
Multiple-Input-Multiple-Output (MIMO) antenna systems are a key enabling technology for 4G wireless
communications and beyond. MIMO antenna systems provide significant data rate increase in multipath
wireless communication systems. The use of multiple antenna elements within the user terminals poses several
challenges with conflicting requirements. While the user handset device size is limited, the integration of
multiple printed antennas is such small devices yields significant coupling and correlation between the antenna
structures and their radiation patterns. Issues such as the correlation coefficient and isolation have direct impact
on the achievable capacity (data rate) of a MIMO communication system and degrades its performance. The
design of novel antennas and coming up with isolation enhancement mechanisms is a topic of continuous
importance. In this talk, we will review some of the metrics needed to characterize MIMO antennas, and then
touch upon some of the recent developments in printed MIMO antenna designs for mobile handsets along with
some of the isolation mechanisms used to improve their performance. Several design examples and prototypes
will be presented and discussed.

The EMBS Chapter of IEEE Kingston Section and Queen’s School of Computing are proud to present the following distinguished lecture:

 

Advanced Ultrasound Imaging and Interventional Photoacoustic Surgical Systems

Date:   Thursday July 24th, 2014.

Time:  2:30 PM - 3:30 PM

Location: Walter Light Hall 210

Speaker:  Dr. Emad M. Boctor, John Hopkins University

Abstract:  In recent years, the use of imaging to make immediate clinical and interventional decisions has grown in both sophistication and adoption. Ultrasound is an ideal imaging technology for such purposes, from the perspectives of cost, mobility, and patient radiation exposure. However, ultrasound scan acquisition remains primarily manual, subject to the skill of a particular physician or ultrasound technician, and time consuming. Additional challenges exist in the use of ultrasound to guide surgical or interventional procedures, including system integration, setup complexity and calibration, precise tracking, and real-time monitoring of a procedure’s outcome. To address these challenges we have developed a collection of novel tracking and ultrasound imaging technologies and integrated these in prototype systems. 

In this talk, we will introduce multiple system embodiments that involve robotics, tracking, ultrasound image processing, elasticity monitoring, and photoacoustic imaging. The underlying themes in these systems are (1) simultaneous tracking of interventional tools and the surgical scene with respect to the US images and (2) monitoring physiological changes, specifically tissue coagulation, throughout the procedure. For the first theme, the talk will include a description of a novel photoacoustic-based surgical tracking system applied to laparoscopic procedures. Also, we will describe a new vision-based ultrasound tracking system applied to biopsy and percutaneous procedures. With respect to the second theme, we will present a precisely-shaped acoustic ablation system under elasticity and 3DUS image guidance. In addition, a new photoacoustic-based brachytherapy imaging system will be introduced.

 

Speaker Bio: Emad Boctor completed the B.Sc. and M.Sc. degrees in Biomedical Engineering from Cairo University, Egypt, in 1995 and 1998. He also earned an MSCS degree in Engineering Mathematics and Computer Science from University of Louisville, Kentucky in 2000. He then received Master’s and Doctoral degrees in 2004 and 2006 from the Computer Science Department of Johns Hopkins University. In 2007, he joined The Russell H. Morgan Department of Radiology and Radiological Science at the Johns Hopkins Medical Institute, where he initiated a research program in the field of advanced interventional ultrasound imaging. Dr. Boctor’s research focuses on image-guided therapy and surgery, a subject in which he has authored and co-authored over 35 peer-reviewed manuscripts, has filed more than 15 pending and issued patents, and has been recognized with numerous awards and fellowships. Dr. Boctor is an Engineering Research Center investigator, and holds a primary appointment as Assistant Professor in the Department of Radiology and a secondary appointment in both the Computer Science and Electrical Engineering departments at Johns Hopkins.  He is an active member of IEEE, SPIE, and the Medical Image Computing and Computer Assisted Interventions (MICCAI) societies and has been a scientific reviewer for many prestigious journals and conferences.

Stored Energy and Current Optimization for Small Antennas

Date:   May 30th, 2014.

Time:  11:00 AM

Location: Royal Military College of Canada, Currie Building, Currie Hall

Speaker:  Dr.Mats Gustafsson (IEEE AP-S Distinguished Lecturer )

Abstract:  Design of small antennas is challenging as the Q-factor, efficiency, and radiation resistance must be controlled simultaneously. In this presentation, current optimization is used to analyze small antennas. The stored energy is expressed in the current density in the antenna structure and the optimal current distribution is formulated as a convex optimization problem. The optimal currents provide insight for antenna design and present performance limits of antennas. We present several optimization formulations such as the maximal gain Q-factor quotient, minimal Q for superdirectivity, minimal Q for given far field, and efficiency. The effects of antennas embedded in structures such as mobile phones are also discussed. Results are shown for different antenna geometries and compared to state of the art designs showing that many antennas perform almost optimally.

Speaker Bio: Mats Gustafsson received the M.Sc. degree in Engineering Physics 1994, the Ph.D. degree in Electromagnetic Theory 2000, was appointed Docent 2005, and Professor of Electromagnetic Theory 2011, all from Lund University, Sweden. He co-founded the company Phase holographic imaging AB in 2004.  His research interests are in scattering and antenna theory and inverse scattering and imaging with applications in microwave tomography and digital holography. He has written over 70 peer reviewed journal papers and over 90 conference papers. Prof. Gustafsson received the Best Antenna Poster Prize at EuCAP 2007, the IEEE Schelkunoff Transactions Prize Paper Award 2010, and the Best Antenna Theory Paper Award at EuCAP 2013. He serves as an IEEE AP-S Distinguished Lecturer for 2013-15.
