This book provides an overview of electromagnetic interference (EMI) topics, along with their challenges and solutions. The author outlines how to effectively control the adverse effects of EMI in modern radio communication systems. The author describes how EMIs have become a problem due to the rapid growth of the number and complexity of radio wireless and IT systems in the environment, and what can be done to mitigate the problems raised. He then describes how EMI emissions result in performance degradation and operation limitations of radio communication and IT systems, especially in the fast-growing 4G-LTE and 5G-NR mobile cellular networks, including WLAN, WIFI, machine-to-machine and Internet of Things (IoT) networks, among other radio wireless networks. Each problem raised is then accompanied by potential solutions. The book can be helpful to technical personnel, who are involved in planning, designing, or maintaining radio equipment and systems. The book can also benefit university students, practicing engineers, and others interested in discovering more about the origins and impacts of EMI phenomena in today’s radio communication systems.

Conclusion.
Miroslav Pajovic graduated from Electrical Engineering School, majoring in RF Communications, at Belgrade University, Yugoslavia. Later, he evaluated his academic level to a Master degree in Electrical Engineering in the USA. After graduation, he worked as a System RF Engineer in several radio centers and facilities in Belgrade, Yugoslavia and Washington, DC, USA. From 1995 to 2020, he worked in several companies in Silicon Valley as a Sr. EMI Engineer. Most of this time was spent in Cisco System, Inc in a position of an EMC Technical leader. During his EMI research and design works in Silicon Valley, he used to be an author of some IEEE Transactions and Conference papers, and EMI and Antenna presentations (that can be found in the IEEE Library), including in-company EMI/EMC research works. Also, he was awarded some USA patents related to EMI-metamaterial filter technology.
