Sohel named 2019 Graduate School Presidential Fellow
Shahadat Hasan Sohel was honored for his work, “High Linearity Power Amplifiers for Next Generation Communication Systems,” as advised by ECE Professor Siddharth Rajan.
The Presidential Fellowship is the most prestigious award to recognize "the outstanding scholarly accomplishments and potential of graduate students entering the final phase of their dissertation research or terminal degree project."
Sohel said he decided to choose Ohio State for graduate school because of the facilities it offers for more hands-on experience.
“The field expert faculties and the top-notch cleanroom facilities provide me with ample opportunity to explore any new idea,” he said. “My advisor, Prof. Siddharth Rajan, has been instrumental in all my research progress. His constant support and feedback help me immensely to work on challenging projects.”
Sohel said the focus of his research is to implement novel channel engineering techniques to demonstrate highly linear power amplifiers, essential for high frequency next generation communication systems such as 5G telecommunication and internet-of-things (IOT).
“Starting from designing and modeling of novel transistor channels using polarization engineering techniques with III-Nitride material system, our research covers till demonstration of fabricated devices,” he explained. “We have been able to achieve state-of-the-art linearity in power amplifiers till date for X-band (8-12 GHz) applications.”
“This could enable a new generation of electronic and communication systems like connected cars in the streets and smart sensors in homes,” he said.
After graduation, Sohel plans to join a research lab, either industry or in academia, where he can continue working on his research.
