Project OverviewI measured the 210 and 220 TM modes of a rectangular cavity resonator
using a vector network analyser. The cavity was made of aluminum with a copper base and top. The dimensions of the cavity are 10.942 cm x 5.104 cm x 1.025 cm.
CalculationsI wrote a Maple program that plots various TM modes for a rectangular cavity and calculates corresponding resonant frequencies. The program can be seen here: Here is a plot of the 210 mode:
Here is a plot of the 220 mode:
To get an idea of the distribution of resonant frequencies, I calculated the resonant frequences up to the 666 mode. They are shown here:
The calculated values for the 210 and 220 modes are: f(210)=6.031 GHz f(220=6.481 GHz
