دانلود کتاب الکترومغناطیس برای تمرین مهندسین

This second edition was targeted specifically for the young professional entering the engineering industry after college or university study. Truth be told, I did not leave Kansas State University (KSU in Manhattan, KS) in 1987 with my BS degree in engineering fully adept at the subject of electromagnetics (EM). This took some initiative on my part, years after graduation. First, in June 1987 I was introduced to some of the finest colleagues a young professional could ever be associated with. These guys introduced me to and taught me about the field of electronic warfare, and I had three good starting years. However, in October 1991, the engineering market changed, and I found myself feeling the need to expand my engineering skills in the areas of radar (1987– 1990), voice and digital radio communications (1992–2000), and electromagnetic theory (2004–2011). Good books on radar and voice/digital radio communications were easily procured. However, the topic of electromagnetics was considerably more difficult to tackle by way of self-study. I chose not to enroll in a university or community college course. Neither did I attend a professional engineering seminar. Instead, I had the good fortune to find procure three important learning resources: 1. A clearly written university-level vector calculus book; 2. An excellently taught YouTube video course titled “Electromagnetics” (24 1-hr lectures) taught by Dr. Harishankar Ramashandran of the Indian Institute of Technology; 3. A clearly understandable Schaum’s Outline series titled, Theory and Problems of Electromagnetics written by Joseph A. Edminister, to tackle EM problem-solutions. It took me four years to go through the full calculus book (800 pages), an additional four months to view and completely learn the contents of the 24 1-hr Ramashandran EM lectures, and another 2 years and 2 months to tackle (and conquer) the problems offered in the Schaum’s Outline book. I devoted anywhere between 15 to 45 minutes a day, even as I worked full-time on radio frequency (RF)/ microwave (MW), electromagnetic compatibility (EMC), and antenna engineering for Boeing. I eventually became so proficient in my skill and understanding of EM that colleagues with master’s degrees and PhD’s in the company would come to me to consult on various EM problems they encountered. In 3 months, the team’s electromagnetic effects (EME) and antennas group manager promoted me to senior principal investigator for the BCA Product Development organization of Boeing (Seattle, WA). I share this with you—not to be boastful—but to illustrate that with enough effort, patience, and perseverance, you, too, can gain proficiency and self-confidence in this subject such that real-world EM problems/obstacles can be overcome in the practical, real-world engineering arena, too. I wish the reader every good success in his/her efforts and future professional endeavors.
