Zur dielektrischen Anisotropie des Naturholzes im großen Frequenzbereich

Kröner, Karl; Pungs, Leo GND

The dielectrical anisotropy of wood (spruce, beech and oak) in absolutely dry condition is determined by measurements of the dielectrical constant in the frequency range of 3 • 10^2 to l0^9 c. p. s. It is found that the anisotropy is mainly caused by the macroscopical structure of wood as a compositum of cellular substance and air. - An anomalous dispersion of the dielectrical constant is found. The variation of the dispersion caused by different directions of the electrical field is explained likewise by the mixed structure.
