  One of the best references is:

  R. F. Harrington, TIME HARMONIC ELECTROMAGNETIC FIELDS, McGraw-Hill,
                    NY, USA, 1961.

  (See Ch. 7 - pp. 365-367). Babinet principle is used to determine
  transmission through apertures in conducting surfaces, such as slots
  on the narrow wall of a waveguide - slotted array antenna. Basically
  it is applied to aperture antennas.

  Other references include

  R. E. Collin, FIELD THEORY OF GUIDED WAVES, IEEE Press (Classic
                Re-issue series), USA, 1991. (ch. 1).
