Department of Electronics and Communication Engineering

Mr. Rajarshi Sen

Assistant Professor

My fascination always lies around how the electromagnetic world around us always peeks into our daily affairs and benefits us! It is a tantalizing endeavor for me to undercover the interesting and hidden physical phenomena related to how EM waves interact with our material world.
