ANALYSIS AND DESIGN OF ANTENNA ARRAYS FOR RADAR AND SPACE COMMUNICATIONS

Date:   Tuesday, November 11th, 2014.

Time:  1:30 PM

Venue: Queens University, MacDonald Hall (See Notes below for directions.)

Speaker:  Dr. Arun K. Bhattacharyya, Distinguished Engineer,  Northrop Grumman Corporation IEEE Distinguished Lecturer, Antennas and Propagation Society Redondo Beach, CA, USA

 

Abstract: In this talk we present an engineering procedure for analyzing and designing antenna arrays. The talk begins with a discussion on designs for beam scanning and steering. Effects of mutual coupling on the performance of an array will also be described. The talk will show how Floquet Analysis can be employed to analyze a finite array to compensate for mutual coupling effects. A step-by-step procedure for aperture arrays and sub-arrays will be presented next. Design examples include patch and horn arrays. A methodology for analyzing multilayered array structures with different periodicities will also presented and applications of such structures in phased array antennas, radar, and space communications will be highlighted.

MODULATION FOR STATIC POWER CONVERTERS

 

Date:   November 6th, 2014.

Time:  2:00 PM – 3:15 PM

Venue: Queens University, Kinesiology 100 (28 Division Street)

Speaker:  Dr. Humberto Pinheiro,  Dept. of Electrical Engineering, University of Santa Maria, RS, Brazil

 

Abstract: This talk will address the modulation for static converters. It starts by reviewing classical “Selective Harmonic” and “Carrier Base Modulation”, their spectra and applications in single phase, in three phases with three and four wires, as well as, in cascade multilevel converters. Then, the degrees of freedom of multilevel converters are explored in a systematic way by using a “Geometric Approach” providing a simple tool for power electronics engineers to explore the entire converter capabilities in the well-known carrier based framework.

Finally, the “Space Vector Modulation” is presented for different converters from single phase to three phase cascade converters where its main advantages and challenges discussed, as well as new concepts, such as time varying space vectors, are introduced.

 

Speaker Bio: Dr. Humberto Pinheiro received the B.S. degree from Federal University of Santa Maria (UFSM), Santa Maria, Brazil, in 1983, the M.Eng. degree from the Federal University of Santa Catarina, Florianópolis, Brazil, in 1987 and the Ph.D. degree, from Concordia University, Montreal, Canada, in 1999.  From 1987 to 1999 he was a Research Engineer of a Brazilian UPS company as well as a professor at Pontifícia Universidade Católica do Rio Grande do Sul where he lectured on Power Electronics. Since 1991, he has been with the UFSM. His current research interests include modulation and control of static converters and drives. Dr. Humberto Pinheiro is a member of the IEEE Power Electronics and Industrial Electronics Societies.

AN INTRODUCTION TO RADIO FREQUENCY AND MICROWAVE ENGINEERING: 

CIRCUIT TO SYSTEM LEVEL

 

Date:   Thursday October 23rd, 2014.

Time:  1:30 PM – 3:00 PM

Venue: Queens University, Jeffrey Hall, Room 127

Speaker:  Dr. Shiban Koul, Professor, Indian Institute of Technology, New Delhi, India.

 

Abstract: In recent years there has been rapid changes in radio frequency (RF) and microwave techniques as well as technology. This trend continuously enables the use of increasingly higher frequencies with their inherent advantages of smaller components and larger bandwidth. In particular, the use of planar circuit architectures and the integration of micro-machining technology has opened up new opportunities in terms of reduction in cost, weight, volume, power consumption as well as the extension of operating frequencies. In keeping with the advances in technology, the engineering design approach is also undergoing a rapid advancement by improved digital signal processing (DSP) techniques and CAD tools. Thus the scope of RF design techniques and technology, that was confined to lower microwave frequencies  (~10 GHz), has expanded to millimeter wave frequencies (30-300 GHz).

The present talk is focused on motivating undergraduate and graduate students to pursue a career in RF and microwave engineering. The lecture starts with the behavior of conventional circuit elements at RF and microwave frequencies and then describes equivalent lumped circuit models for distributed transmission line elements. Different technologies available to the designer will be presented. Starting from conventional microstrip technology, other key technologies, will also be described. Use of modern computer aided design (CAD) approaches to design and develop complex microwave and millimeter wave circuits will also be outlined.

AN INTRODUCTION TO SOFTWARE DEFINED RADIO

 

Date:   Tuesday September 16th, 2014.

Time:  2:45 PM – 4:00 PM

Building: Sir John A. MacDonald Hall, Faculty of Law Building, 128 Union Street

Room: Dentons Canada LLP, Classroom 001 (Basement of MacDonald Hall)

Speaker:  Dr. Jeffrey Pawlan

Abstract: This lecture will begin with the definition, history and evolution of Software Defined Radio (SDR). The lecture will then introduce the concepts of oversampling and undersampling as it applies to SDR. There will also be an introduction to the details of correctly driving and implementing an A/D converter as this is one of the most important components for SDR. Explanations of the firmware and software portions of SDR, and a comparison with state-of-the art conventional analog circuitry, will also be shown. Following these discussions, a live demonstration of SDR will be presented during the talk. Software Defined Radio (SDR) is the culmination of advances on several fronts and probably the most significant area of development in radio systems today. The entire worldwide cellular system uses SDR. NASA and the US military communications are now almost exclusively using SDR. Soon new automobile radios will be SDR to accommodate multiple modulation formats. The role of the electrical and computer engineer in this new technology will be shown so that the audience can adapt and feel that their skills are needed in the evolving field of communications.
