Curriculum Vitae

Josef Knapp was born 1991 in Munich, Germany. He received his Bachelor of Science (B.Sc.) degree in electrical engineering and information technology from TU München, Germany, in 2014 and his Master of Science (M.Sc.) degree in electrical engineering and information technology in 2016, also from TU München, Germany. In 2015 he joined Indian Institute of Technology in Kharagpur, India for one semester. Since February 2016 he is working towards his Ph.D. degree under advisorship of Professor Eibert at the Chair of High Frequency Engineering at TU München.
