Active Metamaterials ― Terahertz Modulators and Detectors

This book covers the theoretical background, experimental methods and implementation details to engineer for communication and imaging application, terahertz devices using metamaterials, in mainstream semiconductor foundry processes. This book will provide engineers and physicists an authoritative reference to construct such devices with minimal background. The authors describe the design and construction of electromagnetic (EM) devices for terahertz frequencies (10⁸-10¹⁰ cycles/sec) using artificial materials that are a fraction of the wavelength of the incident EM wave, resulting in an effective electric and magnetic properties (permittivity and permeability) that are unavailable in natural materials.

Prof. Sameer R Sonkusale is as an Associate Dean of Graduate Education for School of Engineering at Tufts University. He is also an Associate Professor of Electrical Engineering at Tufts University.? Prior to coming to Tufts, he was an Assistant Professor at Texas A&M University, College Station, Tx from 2002 to 2004. For the year 2011-2012, he was also a visiting associate professor of medicine at Harvard Medical School and Brigham and Womens Hospital. Prior to an academic career, he worked? for Texas Instruments from 1996-1997 in Bangalore and in the summers of 1997-2001 in New Jersey and Texas.?

Prof. Sonkusale received his MS and PhD in Electrical Engineering from University of Pennsylvania under the supervision of Prof. Jan Van der Spiegel . He was co-advised by Dr. K. Nagaraj from Texas Instruments and by Prof. Ken Laker at University of Pennsylvania . His undergraduate degree is in Electrical and Electronics Engineering from Birla Institute of Technology and Science (BITS Pilani), India.

Prof. Sonkusale's teaching and research interests are in the area of nanoscale science and engineering, nanoscale sensors-on-a-chip and instrumentation-on-a-chip, low power integrated circuits, biomedical circuits and systems, and analog to information converters. A recent addition to this list is the area of metamaterials and plasmonics.

Prof. Sonkusale received the NSF CAREER award in 2010, the Future Trends in Microelectronics Best poster prize in 2009, and has won several best paper awards with his students at many international conferences (NANO 2008, SENSORS 2008, ISDRS 2009, FTM 2009). He was also the leader of the team that was the finalist at the Semiconductor Research Corporation System-on-Chip design contest in 2006.

Saroj Rout received the B.E. degree in Instrumentation and the M.E. degree in Microelectronics from Birla Institute of Technology and Science (BITS), Pilani, India, in 1996 and 1998, respectively. From 1998 to 2000, he was with the Department Electrical and Computer Engineering at Iowa State University, Ames, Iowa, as a doctoral candidate and research assistant where he worked on low-voltage CMOS analog circuit design.

?

From 2000 to 2007, he was a design engineer at Silicon Laboratories, Inc. where he worked on high performance CMOS and BiCMOS circuits for applications such as Subscriber Line Interface Circuit (SLIC) for VoIP phones, modems for Asymmetric Digital Subscriber Line (ADSL), Direct Access Arrangement (DAA) for PC and embedded modems, RF radio tuners and RF TV tuners.

?

In 2007, he joined the Department of Electrical and Computer Engineering at Tufts University, Medford, Massachusetts, as a doctoral candidate. His current research is in the area of active metamaterials for the terahertz (THz) frequency domain. He has four years of teaching experience at BITS, Pilani and Tufts University, where he taught various electrical engineering courses for undergraduate curriculum.
