Jf. Power et al., Method of Images direct mapping of one-dimensional heat flow patterns in an arbitrarily layered solid, APP PHYS B, 71(1), 2000, pp. 57-67
A new method for direct analysis and visualization of one-dimensional heat
flow patterns in an arbitrarily layered impulse-heated solid is presented.
This analysis is based on the Method of Images in which the surface tempera
ture/time response is described as the superposition of a free medium tempe
rature field and additional image field contributions which account for the
effects of thermal reflection and damping at subsurface interfaces. Throug
h the introduction of a simple set of constraint rules, all sequences of th
ermal reflection and transmission at sample interfaces which return signifi
cant energy to the material surface in a given observation time may be syst
ematically mapped and directly visualized.
