Overview
Hi, my name is Seyed. I completed my BEng degree in Electronics, my first MSc in Electrical Power Engineering from Northumbria University, Newcastle, UK, in 2018, and my second MSc in compound semiconductor electronics as part of CDT programme in Compound semiconductor manufacturing from Cardiff University, Cardiff, in 2020.
I am currently a Ph.D. candidate at Cardiff University's Centre for High-Frequency Engineering (CHFE). I am working on a project titled "Microwave tuneable reflective termination with high power handling" under the supervision of Dr. Roberto Quaglia and Dr. Jonathan Lees. This project seeks to develop a method of solving reflection and matching problems in power amplifiers by using III-V microwave switches as low-loss, tuneable reflective loads.
