Enables readers to grasp the fundamentals of applied electromagnetics through a blended pedagogical approach Electromagnetic Applications for Guided and Propagating Waves comprehensively covers both fundamentals and advanced topics in applied electromagnetics (EM) for the professional, going above the basic static and dynamic EM field theories that are covered in most undergraduate EM textbooks. The textbook introduces complex topics with illustrations of modern technologies that use the topics, followed by a simple presentation of the basic vector analysis and Maxwell's equations, supported by many practical examples, math essays, math puzzles, and the most modern technological developments from the websites of prominent technology companies. The textbook includes review questions at the end of each topic to enhance the students' learning experience and outcomes. It provides the links for multimedia lecture videos and directs students to relevant open sources such as YouTube videos and lecture materials from the prestigious universities of developed and developing nations. The textbook is supported by presentation slides, a solution and instructor's manual, and MATLAB program downloads. Written by prolific teacher Dr. Karmakar, Electromagnetic Applications for Guided and Propagating Waves discusses topics including: * Fundamental theories of resonators, optical waveguides and fibers, antennas and antenna arrays, wireless systems, and electromagnetic compatibility * Electrostatic field theory and detailed derivations of electromagnetic fundamentals such as electric charges and Coulomb's law * Applications of time-varying electromagnetic fields, covering transmission lines, impedance matching techniques, and waveguides * How electromagnetics has impacted our day-to-day life and how we use it in our workplace and on social media * Historical anecdotes and evolution of EM theory from its inception to Maxwell and Hertz Electromagnetic Applications for Guided and Propagating Waves is an essential reference for researchers, professionals, and policy and decision makers in the fields of electromagnetics, electrical engineering, wireless communications, and defense.
Nemai Chandra Karmakar, PhD, is the lead researcher at the Monash Microwave, Antenna, RFID and Sensor Laboratory (MMARS) at Monash University, Australia. He received his PhD in Information Technology and Electrical Engineering from the University of Queensland, Australia, in 1999. He is a pioneer in fully printable, chipless radio-frequency identification (RFID) tags and sensors, readers, signal processing, and smart antennas.
