Over the last 15 years significant advancements in induced polarization (IP) research have
taken place, particularly with respect to spectral IP (SIP), concerning the understanding of …

Thorough knowledge of root system functioning is essential to understand the feedback
loops between plants, soil, and climate. In situ characterization of root systems is …

Resistivity and induced polarization methods are used for a wide range of near-surface
applications, including hydrogeology, civil engineering and archaeology, as well as …

Low-frequency geoelectrical methods include mainly self-potential, resistivity, and induced
polarization techniques, which have potential in many environmental and hydrogeological …

I developed a new model named POLARIS describing the complex conductivity of (pyrite‐
free) shaly poorly sorted sands. This model is based on the solution given by the effective …

The electrical properties of near-surface geomaterials have been hugely important in the
development of many modern welldeveloped countries, and will play a leading role in the …

In electrolyte-saturated sands, the reversible storage of electrical charges is responsible for
a phase lag between the current (injected and retrieved by two current electrodes) and the …

Electric polarization is described as the sum of charge accumulations (free charge density)
and orientation of polar molecules such as those of bound and free water molecules (bound …

Low‐frequency quadrature conductivity spectra of siliclastic materials exhibit typically a
characteristic relaxation time, which either corresponds to the peak frequency of the phase …

Broadband spectral induced polarization (SIP) measurements were conducted at a former
hydrogenation plant in Zeitz (NE Germany) to investigate the potential of SIP imaging to …
