Resumen : | The Koch curve is used in the problem of evaluating and characterizing the electric equipotential lines in the infinite semi-space limited by a rough conducting one-dimensional surface. The solution of Laplace’s equation subject to a constant potential difference between the curve and a straight line placed at infinity is performed with the help of Liebmann’s method. The fractal dimension, Df , of the equipotentials is numerically evaluated with a box-counting method. It is found that Df decays exponentially with distance, from the value Df D 1:273 at the Koch curve to the Df D 1:0 when the equipotentials become flat smooth lines. The method does not depend on the specific choice of the Koch curve to model the rough substrate. |
