Abstract :
The authors thank the commentors for their remarks (see De Zanche et al., ibid., vol.49, p.494, 2002) and for the opportunity to clarify and correct some statements in the subject paper (see ibid., vol.47, p.535, 2000). The principal issue raised by De Zanche deals with a remark that appears the in original paper which seems to suggest that maxima of |E| and maxima of |H| are coincident in a transverse electromagnetic (TEM) resonator. The analysis presented in the original makes it clear that this cannot occur. The periodic nature of the TEM resonator fields is relevant to high-field coil design.
