Abstract:
1. Circuit arrangement comprising: a field generating electrode device which is incorporated into an LC-network and which comprises an electrode surface area arranged in a first plane and that is exposed toward a field space in such a manner that the capacitance of a condenser system which includes said field generating electrode varies in response of the dielectric properties of material present within said field space, an insulator layer extending on a rear side opposite said electrode surface area of said field generating electrode device, and facing away from said field space, a shield electrode device extending on a rear side of said insulating layer and facing away from said field space, wherein the shield electrode device comprises a shield electrode surface area which is arranged in a second plane which is offset from the first plane by means of the insulator layer such that the second plane is not co-planar with the first plane, and a field extinction electrode device which comprises an electrode surface area arranged within the second plane and facing toward an extinction area, wherein said the field generating electrode device and the field extinction electrode device are arranged in such a manner and subjected to electric voltage that the field space and the extinction space partially overlap each other.
