...Qifei Niu; Yu-Hsing Wang ABSTRACT The capacitively coupled (CC) resistivity method is an emerging geophysical technique for near-surface investigations. However, there are two major problems associated with using the CC resistivity (line antenna) system in ground investigations. These two problems...

... through laboratory tests and statistical methods. The relationship between electrical resistance and electrical resistivity is analytically defined by Ohm’s law and Gauss’s flux theorem. Consequently, the underlying importance of electrode capacitance including electrode length and diameter for estimating...

... horizontally in the opposite direction to ∂I/∂t . The CARIS instrument to be described is related to conventional, small-dipole-spacing, galvanic resistivity methods. Conventional resistivity, whether galvanic or capacitive, injects current into the ground that expands in vertical and horizontal...

...Oliver Kuras; Philip I. Meldrum; David Beamish; Richard D. Ogilvy; Deepak Lala Abstract The capacitive resistivity (CR) technique is a generalization of the conventional DC resistivity method that facilitates measurements of electrical resistivity on engineered surfaces and highly resistive ground...

... caused by an interaction between the electric double-layer capacitance and polarization-free pore resistances inside the polarization unit cell, which dominates in the high-frequency interval (approximately 10 kHz–1 MHz). At intermediate frequencies, these two processes combine to yield a transitional...
