Resonance suppression in a TEM cell.

D A Hill, J A Walsh

    The Journal of Microwave Power
    |December 1, 1983
    PubMed
    Summary
    This summary is machine-generated.

    Longitudinal cuts to TEM cell walls suppress specific resonances, enabling enhanced bandwidth for EMC studies. Modified cells are suitable for bioeffects dosimetry at limited higher frequencies.

    Area of Science:

    • Electromagnetics
    • Bio-dosimetry

    Background:

    • Transverse Electromagnetic (TEM) cells are used for electromagnetic compatibility (EMC) and bio-dosimetry studies.
    • Unwanted resonances within TEM cells can affect measurement accuracy.

    Purpose of the Study:

    • To investigate methods for suppressing Transverse Electric (TEmnp) resonances in TEM cells.
    • To evaluate the impact of resonance suppression on the cell's performance for EMC and bio-dosimetry applications.

    Main Methods:

    • Longitudinal cuts were made to the walls of a TEM cell.
    • The effect of these modifications on TEmnp resonances, Transverse Magnetic (TMmnp) resonances, and the propagating TEM mode was analyzed.

    Main Results:

    • All TEmnp resonances were successfully suppressed by the longitudinal cuts.

    Related Experiment Videos

  • TMmnp resonances and the propagating TEM mode remained unaffected.
  • A residual interaction between the suppressed resonances and a biological body inside the cell was observed.
  • The modified cell's effective bandwidth for EMC studies requiring +/- 5 dB accuracy doubled.
  • The modified cell is applicable for bioeffects dosimetry at specific frequencies above the original cell's upper limit.

    • Conclusions:

    • Longitudinal wall cuts effectively suppress TEmnp resonances in TEM cells.
    • The modified TEM cell offers an increased effective bandwidth for certain EMC applications.
    • The cell's utility for bioeffects dosimetry is maintained at a limited range of higher frequencies.
