143 IN MEMORIAM IEEE ANTENNAS & PROPAGATION MAGAZINE AUGUST 2020 Remembering George Ioan Costache Michel Ney and Wolfgang Hoefer G eorge Ioan Costache of Ottawa, Ontario, Canada, passed away on 2 June 2020 at age 77 after living with a significant disability since suffer- ing a stroke in 1995. He leaves behind his spouse Ligia and his daughter Ioana and her family. Prof. Costache was born in Ploiesti, Romania, in 1943. He studied elec- trical engineering at the Polytechnic Institute Bucharest (now Universitatea Politehnica din Bucuresti), Romania, earning the Dipl. Eng. in 1966, and the doctoral degree in electromagnetics in 1974. He remained at the Polytechnic Institute Bucharest as a faculty mem- ber until 1976. From 1976 to 1977, he conducted research in finite element modeling of electromagnetic fields at the University of Manitoba in Winni- peg, Manitoba, Canada. From 1977 to 1985, he worked as a research scientist at Bell-Northern Research in Ottawa, becoming an adjunct professor of elec- trical engineering at the University of Ottawa in 1979. He joined the University of Ottawa full time in 1985 as an associate profes- sor and was promoted to full professor in 1988. During his tenure at the University of Ottawa, he continued his association with Bell-Northern Research as a con- sultant. He also led the Department of Electrical Engineering as acting chair from 1988 to 1989 and as titular chair from 1992 to 1995. In 2008, he achieved the status of professor emeritus. Prof. Costache taught electromagnet- ics and numerical techniques applied to electromagnetics. He was a born teacher who cared deeply about his students and knew how to motivate and encourage them to tackle difficult academic sub- jects, always stressing the importance of clarity, rigor, and imagination in learn- ing. He instilled genuine interest and confidence in his students through indi- vidual attention spiced with infectious humor. Beyond his undergraduate and graduate teaching at the University of Ottawa, he was a coveted teacher of international short courses in compu- tational electromagnetics, notably at the École Polytechnique Fédérale de Lausanne, Switzerland, and at George Washington University in Washington, District of Columbia. Prof. Costache supervised and mentored a successful group of highly qualified Ph.D. and master’s degree students who now hold key positions in industry, government, and academia. Under a series of research grants from the Natural Sciences and Engi- neering Research Council of Canada and the Telecommu- nications Research Institute of Ontario, he and his research team pioneered the applica- tion of emerging numerical techniques, notably finite ele- ment analysis and moment methods, to the study of signal integrity and interference problems in steady-state and time-domain applica- tions to high-speed circuit design. He made original contributions to the solu- tion of skin-effect problems and elec- tromagnetic transient phenomena, and was one of the pioneers who propelled computational electromagnetics into the mainstream of electromagnetic compat- ibility (EMC) during the 1980s and early 1990s. In recognition of his ground- breaking research, he was elected Fellow Digital Object Identifier 10.1109/MAP.2020.3005605 Date of current version: 5 August 2020 George Ioan Costache (1943–2020). Prof. Costache taught electromagnetics and numerical techniques applied to electromagnetics.
