Abstract: We study the asymptotic behaviour of the diffraction problem in the one-dimensional case when the conductivity of one of the two media goes to infinity. By means of heat potentials and Laplace transforms we deduce that the temperature of the good conductor (well-stirred fluid) is spatially constant and we find the related contact conditions between the two media involving time derivatives.
