Reply to "Comment on "Normalization of quasinormal modes in leaky   optical cavities and plasmonic resonators" " by E. A. Muljarov and W.   Langbein
  We refute all claims of the "Comment on "Normalization of quasinormal modes in leaky optical cavities and plasmonic resonators" " by E. A. Muljarov and W. Langbein (arXiv:1602.07278v1). Based entirely on information already contained in our original article (P. T. Kristensen, R.-C. Ge and S. Hughes, Physical Review A 92, 053810 (2015)), we dismiss every point of criticism as being completely unjustified and point out how important parts of our argumentation appear to have been overlooked by the Comment Authors. In addition, we provide additional calculations showing directly the link between the normalizations by Sauvan et al. and Muljarov et al., which were not included in our original article.
