Determination of Charge or Polarization Distribution Across Polymer Electrets by the Thermal Pulse Method and Fourier Analysis.

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)
