Specialization : Microwave Engineering  

Microwave Engineering specialization was offered to the UG, PG and Ph.D. students since the year of establishment (1971) of the Department. Due to significant R&D contributions in this area, DST, Govt. of India sanctioned ~ Rs. 1 crore fund in late 1970’s for the project entitled ‘High Power Microwave Tubes’, Which was later converted to Centre of Research in Microwave Tubes (CRMT) in 1980’s funded by UGC. Further, UGC funded Special Assistance Programme (SAP) at the level of Departmental Special Assistance (DSA) began in 1983 in two thrust areas including Microwave Engineering thrust area. The pace of R&D activities in the area accelerated with the approval of DSA programme by UGC in 1983 and continued unabated till date. After successful completion of the DSA programme in 1988, four phases of UGC funded CAS programmes were sanctioned which included Microwave Engineering thrust area. CAS-Phase-IV programme was terminated in 2012 after conversion of our Institute into an IIT. Sponsored research projects in the areas of Microwave and Millimeter Wave Tubes- TWTs, Gyro-TWTs and Gyrotrons , High Power Microwave Devices for Directed Energy weaponry, Type MM cathodes for Microwave Tubes, Broadband Microstrip Antennas, and Dielectric Horn Antennas funded by DST, MHRD, DOE, DRDO and AICTE have been successfully completed by the Microwave Engineering Group. Starting from the year 1998, on the average more than three Ph.Ds. per year have been awarded and over twenty two (22) research papers per year have been published in international journals/national journals/conference proceedings from this specialization. One DSc degree in Electronics Engineering from this specialization was also awarded in 2006.
