A heat transfer system comprises a substrate (100) and a thin film coating (102) in physical and thermal contact with the substrate (100) at an interface (106). The substrate (100) is configured to transmit thermal waves, and has a first effusivity (µ s ) and a first thickness (T s ). The thin film coating (102) has a second effusivity (µ f ) less than the first effusivity (µ s ), and a second thickness (T f ) less than the first thickness (T s ). |
