The discussion highlights a free book on Electromagnetic Field Theory by Bo Thide, which is designed for a similar audience as Jackson's work but is significantly shorter at about one-third the length. The book features a professional layout and includes numerous figures, along with an accompanying exercises book. Despite its accessibility, concerns are raised regarding inconsistent notation and skipped steps in certain chapters, suggesting it may not be the best resource for students. Thide is noted for his contributions to the application of Orbital Angular Momentum encoding in radio waves. The book is available for download under a restrictive license, with links provided for both the PDF and a previously available HTML version.
