Department of Electrical Engineering (EE) professor Bertrand Hochwald and former graduate student Ding Nie are the recipients of the 2018 Institute of Electrical and Electronic Engineers (IEEE) Antennas and Propagation Society’s (AP-S) Harold A. Wheeler Applications Prize Paper Award. Their prize-winning paper, “Bandwidth Analysis of Multiport Radio Frequency Systems—Part I,” was recognized as the best applications paper published in IEEE Transactions on Antenna and Propagation Journal in 2017.
In their paper, Hochwald and Nie looked at an open question of how to compute frequency limits over which coupled radio-frequency circuits can be matched. This problem has recently become especially relevant with the influx of many such circuits and antennas compressed into cellular telephones and other portable wireless devices. Hochwald and Nie took the lead in extending and expanding a well-known result from the 1940s that applied to a single circuit. In so doing, they showed that coupling between circuits, traditionally viewed as a nuisance, can be advantageous. Their work, which stemmed from Nie’s EE Ph.D. thesis at the University of Notre Dame, has also been awarded and recognized by other IEEE journals and societies. "I am very honored to receive this paper award jointly with Ding, and I am particularly happy for Ding, who did very fine work during his Ph.D. studies that led to the remarkable results contained in the paper," said Hochwald.
