The Green Functions of the time-harmonic radiate field in divisional uniform dielectric are solved by the physics method, and taking the three-layered media for example, equivalence reflectivity and refractive index of the system are given.

A series of general expressions of electromagnetic field of a vertical electric dipole (VED), harmonic time varying, embedded in surface of the first conducting medium of a stratified medium composed of n, linear, homogeneous conducting layers, is presented by applying the zero-order Hankel transform and its inverse transform.

Harmonic field characteristic and components of the thrust are also studied.

Moreover, the induction voltage in the stator windings resulting from the harmonic magnetic field of the inductio.
