Heat transfer in thin metal film under harmonic thermal boundary condition

Heat conduction in thin metal film under high frequency harmonic thermal boundary condition was solved using Laplace transform, which involves the non-classical two-phase-lag heat conduction model. The solution of inverse Laplace transform was obtained by Riemann-sum approximation. Several examples were given and the microscale thermal response in thin metal film was presented. It was shown that the responding temperature is dominated by the characteristic parameter B, and the responding temperature decreases with increasing B if B is between 0 and 0.25, and increases if B is over 0.25.
