What is the reason for this course?

The applications for RF and microwave devices and circuits are growing at a high rate. One visible example nowadays is wireless communications. Other examples include Direct Broadcast Satellite (DBS) TV, Local Multipoint Distribution Services (LMDS, e.g. wireless cable TV and internet), wireless local area computer networks (WLANs), and future satellite communications systems. In addition, as microprocessor clock speeds continue to increase towards the GHz range, electromagnetic and distributed effects are becoming increasingly important in the digital world as well.
