...In electromagnetism, for example, the Helmholtz equation can be derived by decoupling Maxwell’s (macroscopic) equations where u describes the scalar electric field and the scattering function is given by γ = r − 1 where r ≥ 1 is the isotropic relative permittivity, the relative permeability being taken to be 1 and the conductivity being taken to be zero [23]....
