The “Fundamentals of Transmission Lines Handbook” is a comprehensive guide delving into the principles, theories, and practical applications of transmission lines in electrical engineering. Covering impedance transformation, wave guides, and characteristic impedance, it navigates through concepts crucial for designing, analyzing, and maintaining efficient communication systems. Rich with illustrations and examples, it serves as an indispensable resource for engineers and students alike.
Early in my explorations of electricity, I came across a length of coaxial cable with the label “50 ohms” printed along its outer sheath. Now, coaxial cable is a two-conductor cable made of a single conductor surrounded by a braided wire jacket, with a plastic insulating material separating the two. As such, the outer (braided) conductor completely surrounds the inner (single wire) conductor, the two conductors insulated from each other for the entire length of the cable. This type of cabling is often used to conduct weak (low-amplitude) voltage signals, due to its excellent ability to shield such signals from external interference.
