How does the method of image charges work between two conducting surfaces?

[dimensionless]

I'm reading about the method of image charges at

http://en.wikipedia.org/wiki/Method_of_image_charges

The page describes a charge located above a single conducting surface. What happens if the charge is between two conducting surfaces? Does the bottom plate, along with the imaginary charge get reflected across the plate above the real charge? I've typed a simple diagram below.


(+) imaginary charge

------------ imaginary plate

(-) imaginary charge

========== real plate

(+) real charge

========== real plate

(-) imaginary charge

------------ imaginary plate

(+) imaginary charge

Yes. In short, you can do the mirroring in steps. This will ultimately lead to an infinite chain of charges as described in your post.
