  • An experimental study of artificial isotropic chiral media at microwave frequencies 

    Smith, Anthonie Gronum (Stellenbosch : Stellenbosch University, 1994-12)
    ENGLISH ABSTRACT: An artificial chiral medium can be made by embedding metal helices (chiral or handed structures) with random orientation inside au achiral hnst medium. The electromagnetic behaviour of such artificial ...

  • The design of a single rotor axial flow fan for a cooling tower application 

    Bruneau, Phillippe Roger Paul; Von Backstrom, T. W. (Stellenbosch : University of Stellenbosch, 1994-12)
    ENGLISH ABSTRACT: A design methodology for low pressure rise, rotor only, ducted axial flow fans is formulated, implemented and validated using the operating point specifications of a 1/6th scale model fan as a reference. ...
