Abstract
A system for imaging material, typically in an underground scenario, comprising of a plurality of conductive electrodes supported on a conductive substrate positionable in an environment to be imaged, a signal generator connected to at least two of the electrodes, and a signal detector connected to at least two of the electrodes, and wherein an impedance compensator is arranged between each electrode and its substrate to counter parasitic impedance between the two. Typically the impedance compensator may be arranged to act as a negative capacitance, which may be approximately equal to any capacitance between the electrode and the substrate. An electrode may be a drive electrode coupled to a signal generator, or a detector electrode coupled to a detector, or may be reconfigurable to act as either one.
