Abstract :
The concept of lacunarity can be applied to a wider range of geometries as compared to fractal dimension. In particular, a measure can be obtained for both prefractal and non-prefractal curves. The significant analogy between average lacunarity and resonant frequencies observed in the presented results is not sufficient to completely characterize the resonant behavior of a convoluted wire dipole by its average lacunarity or, for prefractal dipoles, by the combination average lacunarity-fractal dimension. However, the existence of a more strict relationship between lacunarity and resonant frequencies cannot be completely excluded, because the average lacunarity Lambda macr may provide only part of the information contained in the lacunarity curve Lambda(r).
