Biography

Ashwita Nair received the M.Sc. degree (cum laude) in electrical engineering from Delft University of Technology (TU Delft), Delft, The Netherlands, in 2021, where she is currently pursuing the Ph.D. degree with the Terahertz Sensing Group. At TU Delft, her research focus is on the use of scanning lens arrays for automotive radars working at high frequency. During her master’s, she worked on analyzing the impact of mutual coupling in integrated lens arrays. Her research interests include the analysis and design of planar antennas, integrated lens antenna arrays, and radar systems.
