Fractal dimension of dielectric breakdown
WebNov 1, 2024 · For U > ca. 7 – 8 V, fractal dimension increases as applied voltage increases. Such behavior may be due to dielectric breakdown [[34], [35]], which is known to naturally lead to fractal structures. At a critical voltage, between 7 and 8 V, dielectric breakdown is triggered and fractal dimension has its minimum value. WebThe fractal dimension was employed to depict the morphological characteristics of branched lightning. Moreover, the box dimension method was adopted to calculate the fractal dimension. ...
