If there are no sources of an electromagnetic field present anywhere in space during a period of time, then that field is said to be a free-field during that time. The detailed properties of such free-fields were first studied in detail by Sherman, Devaney and Mandel, Sherman, Stamnes, Devaney and Lalor, and Devaney and Sherman in the early 1970s. Such fields are of interest because they form the simplest type of wave phenomena encountered in both electromagnetics and optics.
