    Compact high-power broadband absorptive filters using slotted waveguide harmonic pads
    (The Institution of Engineering and Technology - IET, 2014-06) Stander, Tinus; Meyer, Petrie; Van der Walt, Pieter Willem; Electrical and Electronic Engineering
    A compact high-power broadband absorptive filter is designed by cascading a slotted waveguide harmonic pad with a wide stop-band reflective filter. Absorption is achieved by coupling a surface current standing wave to absorptive external auxiliary waveguides through a cascade of transversal broad-wall slots in rectangular waveguide

    Contributions to microwave passive component design
    (Stellenbosch : Stellenbosch University, 2019-12) Meyer, Petrie; Fourie, Coenrad; Stellenbosch University. Faculty of Engineering. Dept. of Electrical and Electronic Engineering.
    ENGLISH ABSTRACT: The dissertation presents an overview of the publications of the candidate and his research group on design techniques and structures for microwave passive networks which have advanced the field in a number of a spects. They have also impacted materially on local industry. The work includes three main activities, namely numerical modelling and analysis of microwave structures, microwave filter applications, and microwave antenna applications. A particular focus is placed on structures supporting multiple propagating modes, as this has been a recurring topic throughout the career of the author. Firstly applied to microwave waveguide filters, h is most r ecent work extends multimodal concepts also to antennas. The modelling of these structures forms a crucial part of the design procedure, and also contributes largely to the ability of designers to exploit this behaviour to achieve added functionality and improved performance.

    Etched ring absorbing waveguide filter based on a slotted waveguide antenna response
    (Wiley, 2008-04) Stander, Tinus; Meyer, Petrie; Electrical and Electronic Engineering
    A cascade of resistively loaded etched rings in waveguide is proposed to act as the load in a balanced FMCW Reflected Power Canceller topology using a slotted waveguide array antenna. A synthesis technique using derived equivalent circuit models, is presented and tested.
