Numerical Mode-Matching （NMM） method is a more effect method in electromagnetic field computation and is more advantageous than other methods. It is successful in stimulation of electrical logs. The theory of NMM is firstly introduced in detail and some research developments and application results are summarized in numerical modeling of electrical logs by way of illustration. Then the basic procedure of NMM is generalized in a way of illustration. Finally, the further applications of NMM in some domain of electrical logs, particularly in 3-D field are prospected.
