**Abstract.**

I will present partial regularity result about a problem involving two positive harmonic functions that meet continuously along a free hypersurface, with a "transmission condition" involving the jump between the gradients of the two functions. In particular I will show how we obtain that the free hypersurface at optimum has finite measure and is C^{{1,a}} on the zero set of the harmonic functions.
