The IEEE Kingston Antennas Propagation (AP) and Microwave Theory and Techniques (MTT) local chapter is proud to sponsor the following Distinguished Lecture:
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.
Speaker Bio: From November 1985 to April 1987, Dr. Arun Bhattacharyya (IEEE F’02) was with the University of Manitoba, Canada, as a Postdoctoral Fellow in the electrical engineering department. From May 1987 to October 1987, he worked for Til-Tek Limited, Kemptville, Ontario, Canada, as a senior antenna engineer. In October 1987, he joined the University of Saskatchewan, Canada, as an Assistant Professor of the Electrical Engineering Department and was then promoted to the rank of Associate Professor in 1990. In July 1991 he joined Boeing Satellite Systems (formerly Hughes Space and Communications), Los Angeles as a senior staff engineer, and was then promoted to scientist and senior scientist in 1994 and 1998, respectively. Dr. Bhattacharyya became a Technical Fellow of Boeing in 2002. In September 2003 he joined Northrop Grumman Space Technology group as a staff scientist, senior grade.
He became a Distinguished Engineer which is a very rare, and honorable, recognition in Northrop Grumman.
He is the author of “Electromagnetic Fields in Multilayered Structures-Theory and Applications”, Artech House, Norwood, MA, 1994 and “Phased Array Antennas, Floquet Analysis, Synthesis, BFNs and Active Array Systems”, Hoboken, Wiley, 2006. He has authored over 95 technical papers and has 15 issued patents. His technical interests include electromagnetics, printed antennas, multilayered structures, active phased arrays and modeling of microwave components and circuits.
Dr. Bhattacharyya is the recipient of numerous awards including the 1996 Hughes Technical Excellence Award, the 2002 Boeing Special Invention Award for his invention of High Efficiency horns, the 2003 Boeing Satellite Systems Patent Awards, and, the 2005 Tim Hannemann Annual Quality Award, Northrop Grumman Space Technology.
Everyone is welcome! Pizza and Light refreshments available to attendees, no RSVP required!
