 terms in a Fourier series, meaning that virtually
 *any* function $f(\vb{k} \cdot \vb{r} - \omega t)$ is a valid solution.

+Keep in mind that in reality $\vb{E}$ and $\vb{B}$ are real,
 so although it is mathematically convenient to use plane waves,
 in the end you will need to take the real part.
