We extend an interferential multilayer model used in optics in the terahertz domain to be able to simulate the mapping of the transmissivity of a multilayer structure of polymers. In particular, we are interested in extracting the thickness gradient of a glue layer within an assembly of polymers. We developed an iterative procedure which we validated by terahertz imaging.
