Helmholtz representation

Web4.2 4.2 Mie Representation. Both Helmholtz representations, Eqs. 45 and 52, apply to any well-behaved vector field F. Another more restrictive representation can be derived if one requests the field F to be solenoidal, as the magnetic field is requested to be because of Eq. 2. Indeed, if a solenoidal field is written in the form of Eq.
