Abstract:

Fourier analysis, applied to the recently introduced thermal pulse method, yields new and unique relations between the time-dependent, pyroelectric response of a thin specimen and the Fourier coefficients of the charge or polarization distribution across its thickness. The new analysis is applied illustratively to thermal pulse data for a vinylidene fluoride copolymer electret. Author
