Dr. Q.J. Zhang, Professor, Carleton University, advanced the theory and practice of active and passive computer-aided design with innovations in linear and nonlinear device modeling and circuit optimization for which he received the IEEE Fellowship. His contributions to sensitivity analysis, design optimization, and knowledge-, neural network- and electromagnetics-based modeling of microwave devices and circuits allowed radio-frequency and microwave designers to conquer prohibitive design tasks. His innovations have globally impacted commercial and military design technologies for satellite ...
