Abstract This paper describes the forward computing method of phaseIP (induced polarization) electromagnetic coupling, which is based on the uniform terrestrial condition. The intermediategradient and dipoledipole device electromagnetic coupling responses are simulated. According to the rule that electromagnetic coupling varies with the working frequency, this paper puts forward an electromagnetic coupling correction means that adopts phases of two frequencies. The effectiveness and the applying effects of the decoupling method are analyzed in combination with practical examples.
