The nanowires consist of polymer photoresist that is structured by direct laser writing (DLW) with two-photon induced polymerization, with radii between $a = 0.5$ and $1~\\mu \\text{m}$. Our flat samples have a thickness up to 9 layers, from $L = 3~\\mu \\text{m}$ to $20~\\mu \\text{m}$. Within each layer, the nanowires are parallel and spaced with random nearest-neighbor distances; nanowires in adjacent layers are perpendicular.
