Department Profile

Department of Electrical Engineering

our eyes once opened, ...we can never go back to the old outlook... But in each revolution of scientific thought new words are set to the old music, and that which has gone before is not destroyed but refocussed.

A.S.Eddington

Electrical Engineering: A Brief History

The study of both electricity and magnetism dates as far back as the work of William Gilbert of Colchester in the sixteenth century. Gilbert showed that many substances such as sulphur, glass and iron, apart from amber, could be magnetized and he was the first to use the terms electric force, electric attraction and magnetic pole. In the seventeenth century, Otto Von Guericke devised a machine that could generate static electricity, and in 1745 Pieter Van Musschenbroek and Ewald Von Kleist independently discovered the principle of the Leyden Jar, in which static electrical charges could be stored. Further to this work, Benjamin Franklin demonstrated, with his famous kite experiment, that lightning is electricity.

The big breakthroughs with electricity, however, lie in the nineteenth century. The most significant accomplishments during this period were due to the extraordinary genuius of Faraday, Maxwell and Hertz that led to recognition of the great underlying force, electromagnetism. Nearly every phase of our lives is touched by Faraday's electric motor, transformer and generator. The first complete electrical DC power system at the historic Pearl Street Station, New York was built by Thomas Alva Edison and it started operation in September 1882.. During 1880s, the development of transformer and AC transmission by L. Gaulard and J.D. Gibbs in France and George Westinghouse in the US led to the introduction of AC systems. It became more attractive with the development of polyphase systems by Tesla. First single phase AC distribution system came into operation in 1886 at Great Barrington, Massachusettes. First single phase AC transmission line was put in Oregon in 1889 and first three phase line in the US came in operation in 1893 in Southern California. During this period, the foundation for the modern electronic revolution was also laid with the invention of Cathode Ray Tube in 1897 by Braun. This was followed by development of transistors (1948) and many other devices, Large Scale/Very Large Scale Integrated (LSI/VLSI) circuits, in the twentieth century. Von Newmann designed and developed the architecture of computers in 1945, the microprocessors came in 1970s and the personal computers in 1980s. The major milestones in the development of communication technologies include the invention of `radio' by J.C. Bose and Marconi in early 20th century and fiber optic communication in 1970s.

The twentieth century has really seen the rapid development of semiconductor, communication and computing technologies, which have revolutionized the modern day high technology industries and drastically changed our life style. Today, the electrical engineering industry has become too large in size and covers many diverse fields. To cope up with this rapid change in engineering education, many conventional engineering institutions have established three separate branches of study, viz., Electrical Power Engineering, Electronics and Communication Engineering and Computer Science.

EE Department at IIT Kanpur

The Electrical Engineering Department was one of the first few Departments with which IIT Kanpur started in 1960. It is currently the largest multidisciplinary Department at IIT Kanpur and covers practically all sub-disciplines under Electrical Power, Electronics and Communications. The Department has, at present, a total faculty strength of 43 against a sanctioned strength of 53, 5 institute research engineers, 3 project research engineers, 36 technical staff, 7 ministerial staff and 9 project staff in addition to the research project employees (such as SRA, RA, etc.) which are about 20 in number.

The Department offers B.Tech, M.Tech and Ph.D Programmes in Electrical Engineering. It also conducts a two semester specialized PG diploma program (DIIT) in video communication systems for Doordarshan engineers. The current sanctioned strength of B.Tech and M.Tech student intake during the first semester, are 82 and 65, respectively and total sanctioned strength of Ph.D students is 40. At present, 22 Ph.D students are registered in the Department and intake of B.Tech and M.Tech students during 1999-2000 first semester have been 81 and 63, respectively. The current active areas of academic programmes and research in the Department include:

Faculty are encouraged to take independent initiatives with collective responsibility in all the relevant academic and R&D dimensions - teaching, curriculum development, graduate research supervision, R&D, continuing education or organization of conferences, symposia, etc. They have ample freedom to associate as members of teams with other faculty, research engineers or with faculty in interdisciplinary areas. Several faculty members of the Department participate in interdisciplinary programmes with colleagues from other Departments or through interdisciplinary centres such as Advanced Centre for Materials Science, Laser Technology, Nuclear Engineering, Environmental Engineering, etc.

The Department conducts sponsored PG programmes for Defence, DRDO, Doordarshan and a select few others. It is getting increasing number of sponsorships from industry for attractive PG scholarships. Faculty are encouraged to participate or bring in University Relations Programmes (URP) from leading industry or organizations. Currently URPs are available with Motorola, Texas Instruments, Silicon Automation Systems and Analog Devices.

Several sponsored projects in many subject areas with large interdisciplinary content are handled through the Advanced Centre for Electronic Systems (ACES), which was started in early 1970s and formally merged with the Department in late 1970s. All Projects Staff - Research Engineers, Associates and Scientific Officers - come under the cooperative umbrella of ACES. ACES encourages better awareness and cooperation across the different Projects in the Department.
