LIKE MOST EEs, YOU PROBABLY WISH YOU HAD A BETTER UNDERSTANDING OF ELECTROMAGNETIC FIELDS AND WAVES. MAYBE THE COMPLEX MATH KEEPS YOU FROM DELVING MORE DEEPLY INTO THE SUBJECT. THIS INTUITIVE TREATMENT GOES LIGHT ON MATH. IN SO DOING, IT BRINGS LIFE TO A TOPIC THAT MANY FIND DRY AND CONFUSING.
UNDERSTANDING ANTENNAS and electromagnetic fields is obviously important in RF engineering, in which capturing and propagating waves are primary objectives. An understanding of RF fields is also important for dealing with the electromagnetic-compatibility (EMC) aspects of every electronic product, including digital systems. EMC design is concerned with preventing circuits ...
