| Abstract: | Using special appearance of EM and IP effects in measured dual-frequency wave form, a square wave coherent method to extract IP effect directly and simutaneously was proposed. The results of numerical calculation and experiments showed that EM effect can be eliminated well in field measurement. The instrument made on this method worked well in waterbath experiments. |
