Abstract
Analysis of an electromagnetic field in a region including an electric conductor having an arbitrary shape is efficiently and accurately performed with a computer. A value of electric potential at a predetermined portion of the electric conductor or a value of the normal component of an electric current density vector to the cross section of a predetermined portion of the electric conductor is used as an initial condition. The distribution of exciting current density vectors in the electric conductor is obtained form the initial condition so as to meet the condition of continuity of electric current. The electromagnetic field of the region is analyzed by using the obtained distribution of exciting current density vectors.
