Karkut for noting the misprints in this reference, which in the present text have been corrected. An alternate two-coil method, with both drive and receive coils on the same side of the film, was presented by B. Jeanneret, J. L. Gavilano, G. A. Racine, Ch. Leemann, and P. Martinoli, Appl. Phys. Lett. 55:2336 (1989).
