1. A miniature meanderline surface coil for use in nuclear magnetic resonance for examination of thin planar or curved layers, comprising:

  • a plurality of parallel, uniformly spaced interconnected elements disposed on a substrate to form a meanderline plane, said elements comprising electrically conductive material is selected from the group consisting of platinum, gold, silver, copper, aluminum, and alloys thereof, each of said element having a length not greater than 1 cm, a width not greater than ½

    mm, and a thickness of less than 0.1 mm, and wherein each said elements is spaced apart by a distance of less than 1 mm, said elements oriented and rotated with respect to an external magnetic field so as to maximize detection sensitivity of said surface coil, and one or more tuning capacitors formed on said substrate.
