A non-contact capacitive sensor probe (10) including a metallic sensor (18) having a first surface opposite a dielectric medium to be sensed; a plurality of active metallic shields (24,26) adjacent to the metallic sensor, each of the active metallic shields having a pattern of grooves (28) inhibiting eddy currents on a surface of the shield, wherein the pattern on one shield (24) does not overlap with the pattern on a second shield (26), and a passive metallic shield (19) adjacent the active metallic shields, such that active metallic shields are sandwiched between the metallic sensor and the passive metallic shield. <IMAGE>
