  • Impulse TDR and its application to measurement of antennas

    McCabe, Steven Owen; Scott, Jonathan B. (IEEE, 2011)
    The traditional stimulus signal used in a time-domain reflectometer (TDR) is a voltage step. We propose an alternative technique, whereby an impulse generator is employed in place of the step generator in a TDR. The advantage ...
  • Measurement of antennas and microwave components using time-domain reflectometry of a voltage impulse

    McCabe, Steven Owen; Scott, Jonathan B. (IEEE, 2011)
    Band-pass microwave systems such as ultra-wideband antennas are traditionally characterized in the frequency-domain through a vector network analyzer in an anechoic chamber. A recent study proved antennas could be accurately ...
  • Measurement of implant electrode leads using time-domain reflectometry to predict the resonant length for MRI heating

    McCabe, Steven Owen; Scott, Jonathan B. (Electronics New Zealand Inc, 2016)
    Magnetic Resonance Imaging (MRI) machines can generate hazardous RF heating of patients with implanted neurostimulation leads. Consequently, most patients with these implants are contraindicated from having MRI scans. The ...
  • MRI Safe Electrodes for Spinal Cord Stimulation (SCS)

    Hartung, Dirk; Scott, Jonathan B.; McCabe, Steven Owen; Single, Peter (2017)
    Adding decoy filars and non-therapeutic decoy electrodes to therapeutic filars can divert and dissipate a significant fraction of captured RF energy in a distributed way along the lead. Simulated worst case local SAR values ...
  • New MRI-safe Implant Electrode Design

    McCabe, Steven Owen; Scott, Jonathan B. (IEEE, 2016-01-01)
    Medical implants often prevent patients having Magnetic Resonance Imaging (MRI) scans because the leads behave as antennas with respect to the RF excitation and cause hazardous heating in neural tissue. This manuscript ...
