Dr. Ranajit Sai is a Senior Researcher at Micro and Nano Systems (MNS) Centre in Tyndall National Institute, Ireland. He is currently the technical lead of the Integrated Magnetics Research group overseeing multiple research projects funded by Semiconductor Research Corp. (SRC), Intel, Applied Materials, NXP, Taiyo Yuden among others. Ranajit received his PhD in an interdisciplinary program – Nanoengineering for Integrated Systems from Indian Institute of Science (IISc), India in 2014. For his dissertation, he designed and developed the best-in-class magnetic-core GHz inductors for which a US patent has been granted. Following his graduation, Ranajit worked ~4 years (04/2014 - 11/2017) in Japan as an Asst. Professor in the Dept. of Electrical Engineering at Tohoku University, Sendai, and another 4 years (02/2018 - 04/2022) in India as a Visiting Faculty in the Centre for Nano Science and Engineering (CeNSE) at IISc, Bengaluru. Ranajit's research and publications have focused on the confluence of microelectronics and material science. It encompasses the design, fabrication, and on-silicon integration of miniaturized and efficient passive devices for power/RF magnetics, EMI/EMC, and sensor applications. His research is driven by probing novel physical phenomena, tailoring material properties, and solving technological bottlenecks through innovation in device design and integration. To date, Ranajit has co-authored 22 journal articles, 7 conference proceedings, and 4 patents. He has presented his research work in more than 30 conferences of international repute that includes the flagship conferences organized by IEEE Magnetics Society and American Institute of Physics. He also has chaired various technical sessions, delivered invited talks, and served as a program committee member in those conferences.

My research theme is to develop miniaturized and efficient electromagnetic devices – with a focus on probing novel physical phenomena, tailoring material properties by structural engineering, and solving technological bottlenecks by innovation in device integration etc. in the field of power magnetics, RF magnetics, nanoelectronics, and sensors.Technologies: Integrated magnetics - design and development of on-silicon and PCB-embedded high-frequency (1-100 MHz) power inductors with indegenously-developed magnetic core 5G EMI/EMC - assessment and management of high-frequency electromagnetic noise by utilizing resonance characteristics of various magnetic materialsSensor - design and fabrication of thin-film and 2D/1D heterostructure based sensing elements for chemiresistive gas sensors and impedance-based bio-magnetic sensorsMaterials & methods: Amorphous ferromagnetic thin films - sputter-deposited CoZrTa- and CoZrTaB-based uniaxial films and laminates; Fe-based high-flux thin films and laminates; high-resistive granular films On-silicon ferrite thin films - superparamagnetic spinel ferrite thin films deposited by a novel microwave-assisted solvothermal thin film deposition for on-chip RF magnetics and 5G EMI/EMC

I am interested in teaching basic as well as advanced UG and PG level courses in the following broad subject areas: Electricity and Magnetism High-frequency magnetic devices and applications Magnetic and dielectric materials and their applications Micro/Nano fabrication and characterizationSensors and transducersI have 4 years of experience in classroom teaching that include 3 years of teaching to visiting international student groups at Tohoku University in Japan at PG level. I'll be eager to work with students from various backgrounds and nationalities, and can design a course-plan and syllabus accordingly to suit the requirements of the stakeholders in consultation with relevant colleagues.
