摘要：

The multipole expansion of a general plane polarised electromagnetic field is derived. This is accomplished by calculating the coefficients of the dynamical multipole expansion of electromagnetic fields, representing generic solutions of the Maxwell equations in a source-free region. The analytical results are confirmed by comparing the suitably terminated expansions to the exact fields.
