WebFeb 28, 2024 · 分形 (Fractal) 是一类几何形状. 它们的特点是在任意小的尺度上都有精细的结构. 分形通常可以由一些简单结构通过不断组合, 分裂形成, 即所谓的自相似性 (self-similar): 任意的局部都有和整体相似的形状. 它们与传统的几何 (点, 线, 多边形, 多面体等)有很大的不同 ... WebApr 10, 2001 · The usefulness of fractal Hilbert curves in antenna geometry is explored here for the first time. Apart from being simple and self-similar, these curves have the additional property of approximately filling a plane. These properties are exploited in realizing a “small” resonant antenna. This approach has resulted in an antenna size smaller ...

The Hilbert curve (also known as the Hilbert space-filling curve) is a continuous fractal space-filling curve first described by the German mathematician David Hilbert in 1891, as a variant of the space-filling Peano curves discovered by Giuseppe Peano in 1890. Because it is space-filling, its Hausdorff … See more Both the true Hilbert curve and its discrete approximations are useful because they give a mapping between 1D and 2D space that preserves locality fairly well. This means that two data points which are close to each other … See more • Hilbert curve scheduling • Hilbert R-tree • Locality of reference See more • Warren Jr., Henry S. (2013).
