Gaurav Varshney finished M. Tech at NSUT-East Campus Delhi, India in 2014 with the specialization in RF and Microwave Engineering and PhD at National Institute of Technology Delhi, India in 2018. Currently, he is serving ECE Department National Institute of Technology Patna, Bihar, India as Assistant Professor since Jan-2020.

 

He worked on the dielectric resonator antennas, the antenna containing the metallic and graphene radiators for microwave, THz and optical domains. He has attained the specialization in design and implementation of functional elements for the different frequency systems and applications. He has published more than hundred articles in the different peer-reviewed journals of high impact including IEEE Transactions, Royal Society of Chemistry, Optical society of America, IoP science and Many more. The diversity of this publications with the limited number of co-authors shows his efforts in the domain of Electromagnetics.

 

He has been a researcher in the domain of THz electronics which brought him to the level of global leaders in this domain. He had worked on Metamaterials and provided multiple innovations in the relevant domains. He is working on the THz functional elements for around last 10 years and provided the multiple concepts in the domain of design and development of THz antennas, filters and sensors. His founding concept of Tunable Terahertz Dielectric Resonator Antennas is being followed by the renowned researchers around the globe. Moreover, he has proposed multiple concepts in the area of designing the absorption-based sensors, specially, the concept of Metal-free absorbers using Graphite has become vital area of research in the current time for developing the ultrathin metal-free packing thin films for THz electronics.

 

Recently, he has proposed the Theory of Merging the Graphene Plasmons to the Cavity Resonance to obtain the tunable hybrid resonator which can help in developing the tunable THz functional elements. The concept of merging the graphene plasmon resonance to cavity resonance allows to confine the heavy electric field in the graphene element hybridized to the metallic or dielectric cavity that can help in controlling the resonance of metallic or dielectric cavity through external electrostatic field. This concept is getting a global attention in the current time and researchers are on its experimental developments.
