So I have been trying to learn how to calculate frequency and speed of a wave. I have this following question which I am not sure how to answer. Can some one talk me through it please.
In this semester I have to design and make a cylindrical resonant cavity working at 4GHz to determine the dielectric constant of a small ball which would be positioned into the cavity. This resonant will be connected to a network analyzer. What dimension should I design and which modes should I use?
