Vikram Sekar, a graduate student in the Department of Electrical and Computer Engineering at Texas A&M University, was awarded third place in the student paper competition at the 2011 IEEE International Microwave Symposium organized by the Microwave Theory and Techniques Society (MTT-S) in Baltimore, Md.
Of more than 205 student papers submitted from around the world, Sekar had three accepted conference papers, two of which were among the 25 nominated for the best student paper award. He also was given a special mention for having two nominated papers, a unique achievement because there has been no other record of a student author having more than one paper nominated at a single conference.
This is the largest conference in the area of microwave and RF technology and receives more than 10,000 visitors each year.
Sekar won his prize for developing a miniaturized frequency-selective device (or a filter) that operates in two frequency bands simultaneously with very high performance. Such devices are useful for systems that work over multiple communication standards in a crowded frequency environment. He demonstrated how half-mode substrate-integrated-waveguide technology could be utilized to implement low-loss filters with excellent interference rejection capabilities, whose sizes are at least six-times smaller in area, as compared to conventional approaches.
Sekar is a Ph.D. student under the supervision of Dr. Kamran Entesari, who also was a co-author in all three papers. Their work was sponsored by National Science Foundation (NSF).
"I am really proud of Vikram's research and I was enjoying working with him,” Entesari said. “He was working very hard especially in the last year of his Ph.D. and was able to publish three IEEE Transactions which is a very good record for a PhD student. His achievement in the prestigious IMS conference is also the result of his dedication to perform state-of-the-art research."
