Abstract:A chopping wave decoupling method was proposed , by which the electromagnetic induction coupling(EM) effect could be directly removed. This method was based on the appearance characteristics of the induced polarization(IP) effect and the EM effect in the measured wave form. The applying conditions and the applying effects of this method were also discussed. Very good decoupling effect in the field had been obtained using the instrument designed on this method.

 

Key words: induced polarization effect; electromagnetic induction coupling; chopping wave method; decoupling method;
