High Power Microwaves and RADAR

Empowered with the high performance computing facility and the powerful 3D EM simulator ANSOFT® HFSS, active research is being pursued in the areas of High Power Microwave sources. Generalised Scattering Matrix (GSM) analysis of microwave devices is also being done in the lab. HFSS simulation, design and fabrication, cold test of Filter loaded and EIK broadband Klystron circuits has been recently completed.

Research is also being pursued on RF power and delivery system for driving Linear Accelerators. Research is also being carried out in the area of RADAR systems.
