The first instance of all acronyms within the main text should be expanded, with the acronym defined after it in brackets, as follows: ‘electromagnetic interference (EMI)’. The expansion should not be capitalised, unless it contains a word that is normally capitalised, i.e. ‘fibre Bragg grating (FBG)’. Once the acronym has been expanded in the main text, all future instances can be shortened to the defined acronym; i.e. ‘EMI’
