 In 2018, the TU Dresden research team presented a conference paper summarizing the results from the most recent experiments on their upgraded test rig, which seemed to show that their measured thrust was a result of experimental error from insufficiently shielded components interacting with the earth's magnetic field.In their experiments, they measured thrust values consistent with previous experiments, and the thrust reversed appropriately when the thruster was rotated by 180°.However, the team also measured thrust perpendicular to the expected direction when the thruster was rotated by 90°, and did not measure a reduction in thrust when an attenuator was used to reduce the power that actually entered the resonant cavity by a factor of 10,000, which they said "clearly indicates that the "thrust" is not coming from the EMDrive but from some electromagnetic interaction."
