Research scholars from the National Institute of Technology – Tiruchi (NIT-T) presented four papers on ‘Microwave Integrated Circuits’ at the recent four-day International Symposium on Microwave and Optical Technology at the University of Delhi that was inaugurated by the former President A.P.J. Abdul Kalam.

The twelfth symposium organised by the University of Delhi in association with the Defence Research and Development Organisation, Jawaharlal Nehru University, IISc Bangalore, IITs Bombay and Delhi, Banaras Hindu University, SAMEER, Bombay, and many other research and development institutions had the participation of about 2,000 scientists from America, Australia, Japan, Korea, Japan, China, Germany, Bangladesh, Russia, France, Italy, Ireland, Spain, Ukraine and Czech Republic.

The role of microwave engineering in the field of health engineering, nanotechnology, space research, domestic applications, biomedical engineering, system on chip technology, and miniaturised antennas were discussed and the possibilities for making the benefit reach the downtrodden was dealt with. Papers were also presented on lasers, optical communication, dielectric antennas, resonators, ultra-wide band antenna and components, numerical techniques, simulation methodologies, integrated optics, filters, couplers and photonic band gap structures.

According to S. Raghavan, Professor, Electronics and Communication Engineering, NIT-T, who was invited as a Session Chair, his group from the institution had the unique distinction of contributing the maximum number of research papers from a single institution at the symposium. The design and applications of meta-materials, new type of materials (having negative refractive index) that does not exist in nature constituted the new work produced by the microwave group of NIT-T. Development of microwave components using metamaterials was the highlight of the four presented papers, said Dr. Raghavan.

In his inaugural speech, Dr. Kalam highlighted the importance of Microwave Engineering and optical fibers in the technological world. Speaking on the topic, ‘Confluence of many spectral bands in the present century’, Dr. Kalam focussed his talk on several frontier areas.

They encompassed MST Radar: an important instrumentation system for atmospheric research; long range radars; futuristic atmospheric research infrastructure; research and technology development in Integrated Missile Development Programme; application of microwave in civil sector; space and defence programmes as growth drivers; deep space communication; space based solar power; terahertz technology; advances in optical technology; and Nanotechnology and microwave development.

The former President exuded confidence that the symposium will succeed in its mission to promote better devices for applications in space science, military and civil society.
