Criticism
The EmDrive was the cover story for the 8 September 2006 issue of New Scientist. After receiving criticism that no peer-reviewed publications on the subject had been made, Mr. Shawyer submitted a theory paper to New Scientist (which is not a peer reviewed scientific journal) Shawyer's paper was almost immediately challenged by Dr. John Costella, a theoretical physicist and electrical engineer who works for the Australian Department of Defence, whose Ph.D. is in relativistic electrodynamics, the field of physics that Mr. Shawyer relies on to support his theory. Shawyer has since published a new theory paper (version 9.4) where the paragraph criticised by Costella is simply omitted.
