Title: Reply to Comment on ‘Energy conservation and the constitutive relations in chiral and non-reciprocal media’
Abstract: We respond to the comment by Mackay and Lakhtakia on our paper. These authors have missed the simple point that our chirality and non-reciprocity parameters are real. The 'inconsistency' claimed by them emerges from their incorrect attempt to apply our results instead to complex chirality and non-reciprocity parameters.
