Abstract

The g11n arrays, which were until now outside of the interest of the geophysicists will be introduced. These so called quasi null arrays can be more effective in detection and characterisation of anomalies have just a small impact on the potential (due to their small size, resistivity contrast to the host rock, and/or their large depth) than the traditional arrays. In many investigations they proved to be even better than the Stummer array which was constructed by an optimisation procedure from the set of the traditional arrays. The g11n arrays proved to be moreover significantly better in horizontal and vertical resolution investigations and in some more models, as well, than even the optimised array. According to our theoretical and numerical investigations the usefulness of these arrays can be expected in numerous other geophysical research areas, as well. It is however already seen that the g11n arrays can be valuable tools for solution of many problems similar to the investigated one, like e.g.: in the research of tunnels, caves, cables, abandoned riverbeds, or discontinuities in the clay layer below a waste deposit. The applications of these arrays require moreover less time to carry out the measurements than those of the traditional arrays.
