Hi.
So I have a few lighthouse tubes and was looking for how they were used in resonant cavities. I came across some diagrams such as the ones shown below. Even though some of them have dimensions, I would like to learn how they found those numbers and also how to calculate dimensions for other resonant cavities. Can anyone recommend some papers or books they have found on resonant cavity design that they found useful?

'Lighthouse' valves were designed to operate with concentric coaxial resonators.
λ/4-Wave Coaxial Resonator Equations are here:
Here is another basic text dealing with coaxial line oscillators which you may find helpful:

This patent of 1953 gives a blow by blow account of a design using only a single - therefore simpler - tuned circuit:
