Using Maxwell equations which are the basic requirement of the electromagnetic wave pro-(pagation,) the authors calculate and analyze some special propagation properties of the electromagnetic wave in the conducting medium.

According to the theory of electromagnetic wave propagation,the problem of inductive communication about passive,unbounded,linear,even,isotropic in conducting medium has been discussed in this article.

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.

Phase relationship between E and H of uniform plane electromagnetic wave in conductive medium;

The paper,accrding to the characteristic of the VLF electromagnetic wave propagation through a dissipative media,introduces the electric properties of several kinds of VLF electromagnetic wave,compares their advantages and disadvantages,and analyzes their input impandance,distributed current and direction coeffecient.

Gauss Theorem and the principles of charge conservation are used to derive the charge distribution of nonuniform conductive medium in electric field.
