- ItemA comparison of simple low-power wedge-type X-band waveguide absorbing load implementations(IEEE, 2007-11) Stander, T.; Van der Walt, P. W.; Meyer, P.; Steyn, W.Two inexpensive waveguide absorbing loads are constructed and measured, each using a single thin resistive sheet absorber supported by styrofoam walls, and 50mm in length. It is found that a V-cut wedge displays less reflection than a tapered wedge, with -30 dB reflection across a band 8.5 - 12.4 GHz.
- ItemWaffle-iron filters with oblique boss patterns(IEEE, 2012-09) Stander, T; Meyer, P; Van der Walt, P. W.; Steyn, W.; Electrical and Electronic EngineeringA waffle-iron filter with an oblique boss pattern is proposed. A circuit model based synthesis method is developed to achieve control over the in-band reflection response. For equivalent filter orders, the boss pattern is found to be more compact than traditional waffle-iron filters.
