| Abstract: | A new decoupled finite element method is suggested to approximate time -dependent eddy current equations in a three - dimensional polyhedral domain. This method is based on solving a vector and a scalar from the splitting of the electric field by using edge and modal finite elements. An optimal energy -norm error estimate in finite time is obtained by introducing a projection operator. |
