Optimal representation of the electromagnetic field is an important and well widely investigated topic. In this lecture, such a problem is discussed under the broader perspective of complexity. This approach is not only conceptually interesting, since it unifies the many different methods used in electromagnetic field representation, but has some practical relevant applications. Examples in antenna measurements, electromagnetic inverse source reconstruction and MIMO channel identification will clarify the potential of the approach. The lecture is based on the following papers:
