Rapidly Convergent Series for the Computation of the Interaction Energy between Dissimilar Plane Parallel Double Layers

  • Zhang Shimin


Several rapidly convergent series for the computation of the interaction energy between dissimilar plane double layers (y0 > yd > 0) are derived by expanding the interaction energy in the power series of ω 0 < tanh(y0/64), the series terms required to obtain the interaction energy with six significant digits do not exceed 1 except C = 2 when the dimensionless surface potential y0 ≤ 20. The results of Devereux and de Bruyn are discovered to be incorrect when y0 and yd are larger, and ξ d is very large or close to −2.00000.
