... Bruce MacA Thomas 11 February 1999 Introduction In this discussion document, the antenna principles underpinning some of the concepts discussed in Ref 1 for the LF-SKA are extended to illustrate the potential difficulty of achieving constant collecting area, and hence the practical realisation of the "magic-carpet" concept. Applications to the "randomised" antenna-element approach to array-station design, and the trade-offs that need to be considered, are briefly discussed. ...
