Waldemar G. Kürten Ihlenfeld joined the National Research
Council Canada in Ottawa, Canada in Feb. 2018 as a Senior Researcher doing investigation work in the field of digital signal
processing, radio frequency and microwaves. From Oct. 1999
to Aug. 2013, he was with the Physikalisch-Technische Bundesanstalt (PTB), Braunschweig, Germany as a Research Group
Leader engaged in research and development of precision
electronic circuits for ac power measurements, mathematical modeling of sampling systems, digital signal processing,
and in investigations on electro-thermal modeling of semiconductor devices. He worked from Sep. 2013 to Feb. 2018 as
a Consultant and Senior Researcher at the Brazilian National
Metrology Institute (INMETRO). He received the M.Sc. and
Ph. D. degrees in electrical engineering from the Braunschweig
Technical University, Germany, in 1995 and 1997, respectively.
