To aid in the ion extraction, the ionic liquid needs a well-defined emission site. To achieve this, tiny emitter tips are micromachined into a porous glass substrate. Propellant is able to wick through the pores of this glass and when it is exposed to the high electric field between the tip and extractor grid, ions are expelled, generating thrust.
