The EmDrive
A New Concept in Spacecraft Propulsion
Satellite Propulsion Research Ltd (SPR Ltd) a small UK based company, has demonstrated a remarkable new space propulsion technology. The company has sucessfully tested both an experimental thruster and a demonstrator engine which use patented microwave technology to convert electrical energy directly into thrust. No propellant is used in the conversion process. Thrust is produced by the amplification of the radiation pressure of an electromagnetic wave propagated through a resonant waveguide assembly.

The experimental superconducting thruster has achieved a Q value of 6.8 x 106 at -195 deg C. This is the highest Q value reported for an HST microwave cavity.
The theory and test results for the EmDrive programme are given in the IAC 2008 conference paper which can be downloaded here:
