Mutual impedance experiments are in situ space plasma diagnostic techniques for the determination of characteristic plasma parameters, such as the plasma density and the electron temperature. These electric experiments rely on the coupling between two emitting and two receiving antennas embedded in the plasma to be diagnosed.Different versions...

Mutual impedance probes and quasi thermal noise spectroscopy are two in situ plasma diagnostic techniques for the measurement of the plasma density and electron temperature in space. Both techniques rely on electric antennas to measure the electric fluctuations coupled to plasma dynamics. Mutual impedance experiments are active techniques. They...

Mutual impedance experiments are a kind of plasma diagnostic techniques for the identification of the in situ plasma density and electron temperature. These plasma parameters are retrieved from mutual impedance spectra, obtained by perturbing the plasma using a set of electric emitting antennas and, simultaneously, retrieving using a set of...

Mutual impedance experiments are active electric instruments that provide in situ diagnostic in space plasmas, such as the plasma density and electron temperature. The instrumental technique is based on the coupling between electric antennas embedded in the plasma, and characterizes the local properties of the plasma dielectric. Different...

The Waves of HIgh frequency and Sounder for Probing Electron density by Relaxation(WHISPER) instrument, is part of the Wave Experiment Consortium (WEC) of the CLUSTER IImission. The instrument consists of a receiver, a transmitter, and a wave spectrumanalyzer. It delivers active (when in sounding mode) and natural electric field spectra....

We study the evolution of a cometary ionosphere, using approximately two years of plasma measurements by the Mutual Impedance Probe on board the Rosetta spacecraft monitoring comet 67P/Churyumov-Gerasimenko (67P) during August 2014-September 2016. The in situ plasma density measurements are utilized to estimate the altitude-integrated electron...

The WHISPER (Waves of HIgh frequency and Sounder for Probing Electron density by Relaxation) instrument has been monitoring the bulk properties of the plasma environment around Earth for more than twenty years. Onboard the 3‐D Earth magnetospheric CLUSTER‐II mission, this experiment delivers active and natural electric field spectra, in a...

Context. During its two-year mission at comet 67P, Rosetta nearly continuously monitored the inner coma plasma environment for gas production rates varying over three orders of magnitude, at distances to the nucleus ranging from a few to a few hundred kilometres. To achieve the best possible measurements, cross-calibration of the plasma...

Mutual impedance experiments are in situ plasma diagnostic techniques for the identification of the plasma density and the electron temperature. Different versions of mutual impedance instruments were included in past and present space missions (e.g., Rosetta, BepiColombo, JUICE and Comet Interceptor). New versions are currently being devised...
