## 3. Boundary conditions and solutionsTo solve Eq. , we first Fourier
transform it in where the Fourier transform is defined by The solution to Eq. that satisfies the mentioned boundary conditions now follows as where is the Fourier transform of the boundary condition , Finally, is obtained by applying the inverse Fourier transform to given by Eq. , The magnetic field components and easily follow from this expression and Eq. , © European Southern Observatory (ESO) 1999 Online publication: November 3, 1999 |
