They're acoustic-like waves in that there's a physical oscillation of particles not like you see in a sound wave. But because you're dealing with charged particles instead of neutral gasses, there's electromagnetic interaction which has an effect on the wave behavior.

When you apply a bias to a Langmuir probe, it drives a current through a small channel in the plasma. The EIC waves depend heavily on gyromotion of ions in the plasma and they damp out if the gyroradius of the ions becomes as large or larger than the size of the current channel.

We're hoping to determine the precise relationship between different sized current channels and critical gyroradii and which specific geometric properties determine the cutoff for different kinds of probes.

Incidentally, any chemists on /sci/ familiar with any gaseous compounds with a similar molecular structure to CO2 (linear, centrosymmetric, covalent bonds) we might be able to use as a substitute?
