Debye potentials

Debye potentials

[də′bī pə′ten·chəlz]
(electromagnetism)
Two scalar potentials, designated Ρ e and Ρ m, in terms of which one can express the electric and magnetic fields resulting from radiation or scattering of electromagnetic waves by a distribution of localized sources in a homogeneous isotropic medium.

To simplify the treatment of general vector problem we first note that any vector field in source-free region can be derived using two scalar functions (so-called Debye potentials), using the prescription described, for example, in [9-11].
where [psi] = [psi] ([rho], [phi], z) represents the sought partial field function (i.e., the Debye potential).
In the absence of light absorption, since the films are very thin (20 [sim] 25 [micro]m), the Debye potentials are considered constant within the film interior.
