The Department of Electronics

University of Science and Technology (CUSAT) instituted the Department of Electronics in the year 1975. This is envisaged as a postgraduate Department with Master's degree and Ph.D. programmes in frontier fields of electronics. The Department was inaugurated by Prof. M. G. K. Menon in 1975.

The Doctoral Programmes are mainly in fields such as Underwater Acoustics, Ocean Electronics, Microwave Propagation & Antennas, Microwave Material Studies, Microwave Image Processing, Pattern Recognition, Microprocessor Applications and Signal processing display devices. External agencies like the DST, ISRO, AICTE, DOE. DRDO,DOD,CSIR,MoES, NRB, DIT and the State Government are supporting this Department through various Research projects and Research Fellowships.

The Department was chosen for special assistance by the UGC under different schemes The University Grants Commission has sanctioned “COSIST” assistance in 1988, to the Department for the development of postgraduate education and research in the areas of Microprocessor Applications and Microwave Antennas. In 1994, the Department was selected by the UGC for Departmental Research Support (DRS) in the field of Ocean Electronics. The Department has been selected for the special assistance programme of UGC at DSA level in the year 2000. Recently, the UGC has recognized the Department as a participant in the Centre of Excellence in Laser and Optoelectronic sciences. The Department is currently undertaking research projects from various agencies and has successfully completed major research projects worth more than one crore. The Department has already established international collaboration with Delft University, Netherlands, Polarizone incorporation, Malaysia, University of Paris, France and University of Kent, U K for different research projects. The research facilities of the department are used by different national research laboratories and research organizations like NAL Bangalore, SAC Ahmadabad, Indian Navy etc.

The Department conducts two symposia as biennial events – the National Symposium on Antennas & Propogation (APSYM – which commenced from 1988 and the symposium on Ocean Electronics (SYMPOL) – from 1991 onwards. Effective from 2007 onwards , SYMPOL, is being organized as international conferences with the technical co-sponsorship of IEEE Oceanic Engineering Society and Acoustical Society of America.

The Department has over 250 research publications and 18 students have taken Ph.D degree during the past five years. It also has very good library facilities having more than 6000 specialized books on Electronics and is also subscribing international and national journals.

The technical biasing of the University, spectacular growth of Electronics industries in Kerala and the location of the University in the industrial zone of the State are all favourable aspects for substantial development of this Department.

RESEARCH AND TRAINING LABORATORIES OF THE DEPARTMENT.

With special assistance from the Ministry of Human Resource Development, Govt. of India, three special Research and Training Laboratories have been set up in the Department in frontier areas of Electronics.

A. MICROPROCESSOR LABORATORY

This Laboratory was set up with aid from the Ministry of Human Resource Development, Government of India. A total grant of Rs.30 lakhs has been sanctioned for setting up this centre. Research work undertaken in this centre are in the areas of Multiprocessors, Protocols for Multiprocessors, Speech Processing, Pattern Recognition, etc.

B. OCEAN ELECTRONICS LABORATORY (CUCENTOL)

A Research and Training Laboratory in Ocean Electronics (CUCENTOL) has been set up in the Department with the financial assistance from the Ministry of Human Resource Development, Govt. of India and the UGC. Developments of new Underwater Transducers and Arrays for Sonar Applications are the major activities of the centre. Simulation of Rotating Hydrophone arrays and Localisation of the Underwater Targets Using Buoy Systems and Estimation of DOA Using the Buoy System are also undertaken in this laboratory. Works in the area of Underwater Target Classifier Capable of Reducing Self-Convolution Distortion, Towards Improving the Space Reconstruction of Underwater Signals, Collection and Analysis of Ocean Noise Data Using NI cDAQ 9215 and NI LabVIEW as well as OROS OR-36 Based Platform for Recording and Analysing the Ocean Noise Data is also undertaken in the lab.

C. MICROWAVE ELECTRONICS AND ANTENNA LABORATORY

A well established research and training Laboratory in Microwave Electronics and Antennas has been set up in this Department with financial assistance from MHRD, UGC, DST (Govt. of India) and DoE (Govt. of India). The Laboratory is equipped with most modern and sophisticated equipment like HP 8510 B Network Analyzer, Agilent Network Analyser 67 GHz, Cascade Probe Station, Microwave Power Meter and different antenna and RCS standards. The laboratory is having a Microwave Anechoic Chamber for simulating free space environment for antenna and RCS measurements. The Chamber has instrumentation set-up attached to it with provision for fully automatic measurement based on HP 8510 B Network Analyzer and Scientific Atlanta Positioner. The Department has developed an indigenous software which is used for quick and precise antenna measurements and analysis. The major areas of research now being pursued are microstrip antennas and transmission lines, super- conducting microwave transmission lines, integrated circuits and antennas, reduction of radar cross section, microwave non-destructive testing, leaky wave antennas, microwave horn antenna, material studies in microwave region etc. Non-destructive testing of objects like vehicular tyres is a break through by the laboratory in NDT technique. These facilities are being used/operated by many establishments like SAMEER (Bombay & Madras), SAC Ahamadabad, NPOL, Cochin, Delhi University, CSIR Regional Research Laboratory (Trivandrum), Jadavpur University, Gulbarga University and others. Major works undertaken are:

  • Electrically Small Antennas
  • Substrate Integrated Waveguide
  • Miniature Antenna for Medical Applications:
  • RFID Tags
  • Ultra Wide Band Antennas
  • Low Radiation Hazard Antennas for Mobile Applications
  • MIMO Antennas
  • Microwave properties of nano composite
D. Embedded System Laboratory (ESL)

The Department has set up an Embedded Systems Laboratory, comprising of Martin Auto vision Expert 9.5 SMD Re-workstation, Tektronics 34 Channel Logic Analyzer, Tektronics Digital Storage Oscilloscope, etc.. The nature of activities currently being pursued in the Department making use of these facilities include the design and development of Embedded Systems for the realization of steering/control system for hydrophone arrays, embedded signal processor modules, embedded CDMA transceiver modules, miniaturized archival tags for tagging tuna, development of miniaturized embedded global positioning devices, etc..
