  • 3D-printed Acoustic Directional Couplers

    MacDonell, Marcus Scott Glengarry; Scott, Jonathan B. (2014)
    Acoustic Directional Couplers permit separation of forward and reverse sound pressure waves. This separation opens the way to traceable precision acoustic reflection measurements. In order to span the audio frequency range, ...
  • Development and Basic Calibration of an Acoustic Vector Network Analyser

    MacDonell, Marcus Scott Glengarry; Scott, Jonathan B. (2017)
    This project aims to develop a method that drastically improves measurement of the acoustic properties of objects. Previously research at the University of Waikato has made progress with acoustic technologies as a precursor ...
  • Realizing an Acoustic Vector Network Analyser

    MacDonell, Marcus Scott Glengarry; Scott, Jonathan B. (2019)
    Acoustic absorption, reflection, and transmission is typically measured using an impedance tube. We present the design and initial measurements of a radically different measurement system. The instrument builds on the rich ...
  • Scaling acoustic directional couplers using 3D printing

    MacDonell, Marcus Scott Glengarry (University of Waikato, 2015)
    Acoustic directional couplers permit separation of forward and reverse sound pressure waves. This separation opens the way to traceable, precision acoustic reflection measurements. In order to span the audio spectrum, ...
  • Waveguide joint design and validation for use in acoustic vector-corrected network analysers

    MacDonell, Marcus Scott Glengarry; Scott, Jonathan B.; Basnet, Keshav (2019)
    The Vector-corrected Network Analyser (VNA) has been an indispensable tool for many decades in the field of RF and microwave engineering where the availability of calibrated and traceable results is taken for granted. ...
