A transmission matrix T is defined as a computational aid for determining refractive indices from the Fourier coefficients of the reflected amplitude in thin-film synthesis. It is shown that the matrix T acts as the term factor in geometric series expansions of the reflected and transmitted amplitudes for a stack of films of equal optical thickness.
