Why are YIG spheres spherical and not cylindrical?
The image is from https://www.qsl.net/ct1dmk/wbond_ex.html about halfway down, at the section "Dual YIG oscillator (HP) wide band coverage from 2 to 20GHz". Some fantastic nerd porn.
My question: I would have assumed that a cylinder would work as a YIG, e.g. with the bond wires half 'wrapped' around a cylinder.
But I've only ever seen YIG spheres. No cylinders. Is this for electrical reasons or because, for example, it's easy to shape and polish a YIG in a ball mill (compared to trying to turn the hard garnet on a lathe)?
