Slow wave structures have uses in several areas, as linear accelerators used for atomic studies and in medical applications, vacuum tubes and as microwave filters. An adequate understanding of this topic requires knowledge on microwave engineering, physics and instrumentation, which is hardly possible to be covered during normal physics or engineering undergraduate courses. This article aims to explore this topic using a circuit analogy and also a 3D electromagnetic field solver. A laboratory experiment is proposed to have a hands-on experience as well. The laboratory test requires common electronic instrumentation and it is easily constructed.
