Binboga Siddik Yarman, Tokyo Institute of Technology Professor Binboga Siddik Yarman is currently on a sabbatical in the Department of Physical Electronics, at the Tokyo Institute of Technology, Japan. His full-time position is with the Department of Electrical and Electronics Engineering, at the College of Engineering, Istanbul University. Professor Yarman is very experienced in the field of communication networks, being one of the first engineers to establish computer-aided design (CAD) tools for constructing practical broadband matching networks and multistage microwave amplifiers for optimized communication systems. In doing this, he paved the way for the generation of CAD algorithms to construct practical circuits in the field of communications engineering, including commercial and military communication sub-systems such as antenna matching networks, and multistage microwave amplifiers for mobile and fixed communication systems. He has published a number of book chapters and journal papers on the design of microwave amplifiers, modeling techniques and other design issues concerning power transfer networks, including a section on 'Broadband Networks' for the Wiley Encyclopedia of Electrical and Electronics Engineering (Vol II, 1999). He has also lectured to both students, and practising engineers on these topics for the last 25 years, in Europe, the USA and Japan.
