We have fabricated and studied superconducting wire networks with various geometrical properties including fractal, periodic, quasi-periodic, and random. We will discuss design and fabrication of these aluminum networks, which consist of nearly one million elements and span a square millimeter. We will present results of several studies of these networks.
Bibliographical noteFunding Information:
Fabrication of these wire networks begins with preparation of the pattern data. Typically this is accomplished by coding an appropriate algorithm in a high-level language such as Pascal or Fortran. Structured languages which allow recursion are particularly useful in defining fractal patterns which are self-similar. or recursive.
