A multi-dimensional systems technique is introduced in this paper for the time-domain solution of low-frequency electromagnetic field problems. The new method establishes a wave equation formulation and in contrast with existing approaches offers precise results even when the frequency range of interest lies at the low end of the spectrum. Launching a discretization process, based on spatially interconnected systems theory, the specific algorithm leads to a robust framework for the analysis and generalization of all time-domain schemes. Numerical verification confirms the preceding assertions and reveals the advantages of the proposed method.

Praca przedstawia metodę wielowymiarowych równań falowych do rozwiązania problemów pola elektromagnetycznego niskiej częstotliwości w dziedzinie czasu. Nowa metoda gwarantuje dokładne wyniki nawet w przypadku gdy rozważana częstotliwość jest krańcowo niska. Wyniki symulacji numerycznych potwierdzają krzepkość proponowanej metody i skuteczne działanie.
