Tapan Kumar Sarkar (August 2, 1948 – March 12, 2021) was an Indian-Americanelectrical engineer and professor emeritus at theDepartment of Electrical Engineering and Computer Science atSyracuse University. He was best known for his contributions tocomputational electromagnetics andantenna theory.

Sarkar was the recipient ofIEEE Electromagnetics Award in 2020.

Sarkar was born on August 2, 1948, inKolkata,India. He obtained hisBachelor of Technology fromIIT Kharagpur andMaster of Engineering fromUniversity of New Brunswick in 1969 and 1971, respectively. He received hisMaster of Science andDoctor of Philosophy degrees fromSyracuse University in 1975.^[1]

Between 1975 and 1976, Sarkar worked for TACO Division ofGeneral Instrument. Between 1976 and 1985, he was a faculty member atRochester Institute of Technology; he also briefly held a research fellowship position at Gordon McKay Laboratory for Applied Sciences inHarvard University in between 1977 and 1978.^[1] In 1985, he became a professor at Syracuse University and held the position until his death^[2] in 2021.^[3][4]

Sarkar acted as an associate editor for theIEEE Transactions on Electromagnetic Compatibility in between 1986 and 1989 and forIEEE Transactions on Antennas and Propagation in between 2004 and 2010. He was the 2014 president ofIEEE Antennas & Propagation Society^[3] and the vice president of the Applied Computational Electromagnetics Society (ACES). Sarkar also served as board member for journals such asDigital Signal Processing,Journal of Electromagnetic Waves and Applications andMicrowave and Optical Technology Letters.^[2] Sarkar was the president of OHRN Enterprises, Inc., an incorporated business specializing in computer services and system analysis.^[2]

He died on March 12, 2021, inSyracuse, New York.^[3][4]

Sarkar's research interests focused on "numerical solutions ofoperator equations arising in electromagnetics andsignal processing with application to system design." He is the author or co-author of more than 380 journal articles, as well as 16 books and, 32 book chapters.^[2] Along with his doctoral student Yingbo Hua, he developed thegeneralized pencil-of-function method forsignal estimation with complex exponentials. Based on Sarkar's past work on the original pencil-of-function method, the technique is used in electromagnetic analyses of layered structures, antenna analysis andradar signal processing.^[5] He is also the co-author of the general purposeelectromagnetic solver,HOBBIES.^[6]

In 2010, Sarkar was chosen as the IEEE Distinguished Lecturer in Antennas and Propagation Systems.^[7] In 2020, he receivedIEEE Electromagnetics Award "for contributions to the efficient and accurate solution of computational electromagnetic problems in frequency and time domain, and for research in adaptive antennas."^[8] He previously was the recipient of Best Paper Awards of theIEEE Transactions on Electromagnetic Compatibility in 1979 and National Radar Conference in the 1997.^[2]

Sarkar receivedhonorary doctorate degrees fromBlaise Pascal University,Technical University of Madrid andAalto University, respectively in 1998, 2004 and 2012.^[8]
