Abstract :
As the electromagnetic measurement while drilling (EMMWD) becomes a popular researching subject, the numerical solution to wire antenna in inhomogeneous media has been the key of the numerical analysis for this technology. In this article, the NMM method is combined with the wire antenna theory for the first time, which is used to solve the Green´s function in layered media. With the advantage of NMM method fully taken to solve the problem in two-dimensional axisymmetric inhomogeneous media structure, a theoretical model and numerical method is established which is suitable for the analysis of wire antenna especially working at low frequency in inhomogeneous media, laying a foundation for the research of EMMWD technology. Besides, the experiment of the source´s equivalence principle in the near field applications is also carried out.
