Introduction:
The microwave is a term used to identify a portion of electromagnetic waves in frequency spectrum ranging from 1 GHz to 300 GHz. Microwave finds its application in the field of Radio astronomy, Remote sensing, Long- distance communication, Space systems, Radar systems, Medical equipments and Missile electronic systems. Applications of microwave other than in the field of communications are enormous and continue to grow. The field of microwave has come to a stage of rapid growth because of the demand to enter into the high frequency regime along with other supporting technologies such as computers and integrated circuitry, MMIC etc and software providing the facility to overcome the many old design difficulties.

As a result of accelerating rate of growth of microwave technology in research and industries, students who are preparing themselves for and the electronic engineers who are working in, the microwave area are faced with the need to understand the theoretical and experimental design and analysis of microwave devices circuits and systems. The lack of which creates problem for aspiring students to get an opportunity to work in the challenging field of microwave.

To fill the gap in the knowledge base in microwave, the ICRS has adequate facilities to provide the required knowledge to the aspirants. Using these facilities of ICRS the participant will be able to improve and enhance their knowledge base. This will be possible as they will handle and operate microwave instruments operating from 1.6GHz to 40GHz. The training will be imparted by the experts who will share their actual experience in the field of microwave.

 
Objectives:
Microwave is a fascinating subject which is useful in Radio astronomy, Remote sensing, Long- distance communication, Space programme, Radar systems, Medical equipments and for other applications.
