Yes, the potential across the closer of the the two sides of a slot is
saying the same thing as
the potential across the longest sides. i.e. the closer of the two sides of
a slot are the
longest sides of that slot.
And technically speaking, babinet's principle is concerned with optics.
Taking
One approach to take for small apertures in solid sheets is to reverse
the model. That is model the equivalent dipole, you will have far fewer
elements and no meshing issues. Due to the duality between E and H
known as Babinet's priciple, this is vaild method.

The way slots work is to put amaximum differential between the longest
sides.
If the impinging wave puts a circulating current laterally across the slot,

Ed,
thanks you did give me the answer I was looking f
actually want to increase the signal that passes through an aperture. I will
be interested to see what others tell us.

I have a question on apertures. You may recall the formula that is frequently
given for signal attenuation through a small aperture in a large conductive
sheet. It is 20LOG(I/2L), where I is the wavelength and L is the slot length.
For example, if x is 1/2-wavelength then the attenuation is 0 dB
