We saw in Chapter 4 that the equations of magneto-quasi-statics are useful for describing waves when the wavelength in the medium is very different from that of an ordinary electromagnetic wave at the same frequency. We will now elaborate on this idea and show how the magneto-quasi-static approximation can be used to analyze modes in a variety of geometries.
