New for July 2006! We
don't have much to offer on this topic yet. If you have any info
please send it in and we'll post it.
A resonant cavity forms a means
of storing electromagnetic energy, at a particular frequency within
a small bandwidth. A resonant cavity must be constructed of a good
conductor, and the shape of the cavity is related to the frequency
that it can resonate at.
Resonant cavities can be categorized
into two types: wanted and unwanted! In the unwanted case, microwave
modules that are improperly designed end up having spurious responses.
Microwave tubes and waveguide filters
are examples of resonant cavity by design. So is a wavemeter!
While we're waiting for further
inputs on this subject, here's a MATLAB (c) file that was contributed
by our friend Itzik. It calculates the resonances of a cylindrical
