| Zusammenfassung |
| We present the high-frequency properties of the eight electric field sensors as
proposed to be launched on the spacecraft "RESONANCE" in the near future. Due
to the close proximity of the conducting spacecraft body, the sensors (antennas)
have complex receiving features and need to be well understood for an optimal
mission and spacecraft design. An optimal configuration and precise
understanding of the sensor and antenna characteristics is also vital for the
proper performance of spaceborne scientific instrumentation and the
corresponding data analysis. The provided results are particularly interesting
with regard to the planned mutual impedance experiment for measuring plasma
parameters. Our computational results describe the extreme dependency of the
sensor system with regard to wave incident direction and frequency, and provides the
full description of the sensor system as a multi-port scatterer. In particular,
goniopolarimetry techniques like polarization analysis and direction finding
depend crucially on the presented antenna characteristics. |
