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.
