Long-wire traveling wave antennas, hundreds of wavelengths long, are used in low-frequency radio telescopes to capture cosmic emissions. The beam tilt calculation from Walter’s text is critical for source localization.

Carlton H. Walter’s Traveling Wave Antennas (McGraw-Hill, 1965) is prized because it bridges pure electromagnetic theory with practical engineering design.
Techniques to efficiently launch waves onto the guiding structure. C. Leaky Wave Antennas
Because they do not rely on resonance, TWAs inherently offer much wider operating bandwidths than standing wave antennas (like half-wave dipoles). Surface Waves vs. Leaky Waves : Hosts a "Cleaned and OCR'ed" version (approx
: Designing antennas that maintain performance over a broad frequency range. Microwave Engineering : Foundational theory for satellite and radar systems. specific technical reports by Walter that focus on a particular antenna type, such as leaky wave
Walter classifies traveling wave antennas based on the nature of the wave traveling on the structure.
