    "abstract": "I consider the quantum electromagnetic field in a coaxial cylindrical\nwaveguide, such that the outer cylindrical surface has a time-dependent radius.\nThe field propagates parallel to the axis, inside the annular region between\nthe two cylindrical surfaces. When the mechanical frequency and the thickness\nof the annular region are small enough, only Transverse Electromagnetic (TEM)\nphotons may be generated by the dynamical Casimir effect. The photon emission\nrate is calculated in this regime, and compared with the case of parallel\nplates in the limit of very short distances between the two cylindrical\nsurfaces. The proximity force approximation holds for the transition matrix\nelements in this limit, but the emission rate scales quadratically with the\nmechanical frequency, as opposed to the cubic dependence for parallel plates.",
