摘要
To solve radiation problems in time domain directly the modal representation of transient electromagnetic fields is considered. Using evolutionary approach the initial nonstationary three-dimensional electrodynamic problem is transformed into the problem for one-dimensional evolutionary equations. The modal basis for electromagnetic fields with arbitrary time dependence in spherical coordinate system is constructed. After elimination of the radial components of electrical and magnetic field from Maxwell equation system the four-dimensional differential operators are formed. It is proved that the operators are self-adjoint ones. The eigen-functions of the operators form the basis. The completeness of the basis is proved by means of Weyl Theorem about orthogonal splitting of Hilbert space. The expansion coefficients of transient electromagnetic field are found from the set of evolutionary equations.
