About me


I am a Post Doctoral Research Assistant at the Antennas and Electromagnetics Research Group at Queen Mary University of London . I have finished my Doctoral studies from same, jointly supervised by Dr.Khalid Z. Rajab and Prof. Yang Hao.

I am interested in non-Foster circuits and its applications in antenna design, high impedance surfaces and active electromagnetic absorbers. I am particularly interested in tailoring of meta-materials using circuit approach.

I have done my Master degree in Microwave Engineering, Department of Electronics Engineering, Indian Institute of Technology BHU , Varanasi, India in 2009. I started my career with couple of RF startups as a Microwave design engineer. Prior to the start of my Doctoral studies, I was working with Broadcom Corporation as a RF/Wireless staff Engineer.

I will use this website to share my research and publications. For any questions about my research or anything else, feel free to contact me on the email address mentioned above.
