There are different sources for an overview on the theory and applications of characteristic modes, including the following:
- A Wikipedia page on Characteristic Mode Analysis.
- A recent thesis on systematic antenna design using characteristic modes
- Overview papers on this topic found in the IEEE Antennas and Propagation Magazine
