Department of Electromagnetic Field

Synopsis:

The subject is devoted to principles of rf. and microwave technology with special attention to measurement problems. It introduces to basic parameters characterising rf. and microwave circuits. It makes familiar with measurement of these parameters and with basic principles of measurement instruments. Exercises contain computer simulations based on measured data and real measurements on professional microwave instruments. It is designed for students who meet the rf. technology for the first time.
