AN INTEGRAL SOLUTION FOR THERMAL-DIFFUSION IN PERIODIC MULTILAYER MATERIALS - APPLICATION TO IRON COPPER MULTILAYERS/

A closed-form solution for heat transfer through a periodic multilayer material utilizing a transfer matrix technique is presented. The bene fit of this technique for periodic multilayer samples is that the use of eigenvector decomposition significantly simplifies the solution. Ex perimental results, obtained in the vicinity of 1200 K on samples comp osed of 10 bilayers of nominally 2/3 mu m copper and 4/3 mu m iron on 75-mu m molybdenum substrates, are presented.
