ABSTRACT
The next part of the book is a long and rather tedious account of some basic theory that is necessary to make calculations of the properties of multilayer thin-film coatings. It is perhaps worth reading just once, or when some deeper insight into thin-film calculations is required. To make it easier for those who have read it to find the basic results or for those who do not wish to read it at all, to proceed with the remainder of the book, the principal results are summarized, beginning on page 52.
