The polarizability of these materials is very low and the frequency range of interest extends from 1 mHz to some kHz. In order to decrease the measurement time, especially for the low frequencies, mathematically orthogonal signals injected simultaneously at all current electrodes will be used. In this contribution, we will discuss the advantages and disadvantages of the method in view of geophysical applications, present a system realization and illustrate the performance regarding the measurement time and phase accuracy in tomographic images. 000139376 536__ $$0G:(DE-HGF)POF2-246$$a246 - Modelling and Monitoring Terrestrial Systems: Methods and Technologies (POF2-246)$$cPOF2-246$$fPOF II$$x0 000139376 7001_ $$0P:(DE-Juel1)129472$$aHuisman, Johan Alexander$$b1$$ufzj 000139376 7001_ $$0P:(DE-Juel1)133890$$aGlaas, Walter$$b2$$ufzj 000139376 7001_ $$0P:(DE-Juel1)142562$$avan Waasen, Stefan$$b3$$ufzj 000139376 909CO $$ooai:juser.fz-juelich.de:139376$$pVDB 000139376 9101_ $$0I:(DE-Juel1)ZEA-2-20090406$$6P:(DE-Juel1)133962$$aZentralinstitut für Elektronik$$b0$$kZEA-2 000139376 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)133962$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000139376 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)129472$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000139376 9101_ $$0I:(DE-Juel1)ZEA-2-20090406$$6P:(DE-Juel1)133890$$aZentralinstitut für Elektronik$$b2$$kZEA-2 000139376 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)133890$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000139376 9101_ $$0I:(DE-Juel1)ZEA-2-20090406$$6P:(DE-Juel1)142562$$aZentralinstitut für Elektronik$$b3$$kZEA-2 000139376 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)142562$$aForschungszentrum Jülich GmbH$$b3$$kFZJ 000139376 9131_ $$0G:(DE-HGF)POF2-246$$1G:(DE-HGF)POF2-240$$2G:(DE-HGF)POF2-200$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bErde und Umwelt$$lTerrestrische Umwelt$$vModelling and Monitoring Terrestrial Systems: Methods and Technologies$$x0 000139376 9141_ $$y2013 000139376 9201_ $$0I:(DE-Juel1)ZEA-2-20090406$$kZEA-2$$lZentralinstitut für Elektronik$$x0 000139376 9201_ $$0I:(DE-Juel1)IBG-3-20101118$$kIBG-3$$lAgrosphäre$$x1 000139376 980__ $$aconf 000139376 980__ $$aVDB 000139376 980__ $$aUNRESTRICTED 000139376 980__ $$aI:(DE-Juel1)ZEA-2-20090406 000139376 980__ $$aI:(DE-Juel1)IBG-3-20101118 000139376 981__ $$aI:(DE-Juel1)PGI-4-20110106 000139376 981__ $$aI:(DE-Juel1)IBG-3-20101118
