The analysis of electromagnetic propagation and scattering from axially symetrical, two dimension-layered media with arbitrary N planar layers in a vertical direction and cylindrical layers in a radial direction has been made. The numerical mode matching theory is used to simplify computation. In this method the discrete numerical eigenmodes are used in a radial direction and the mode matching method is used in a vertical direction to derive the recurrent expressions of the field. This half-analytical and half-numerical method avoids a large amount of computation of two dimensions as the infinite element method. The subsurface electrical parameter profile can be rebuilt by using the numerical results of the field. This method can be used as a computer aid explanation tool for induced logging and deep propagation logging. -from English summary
