In this paper we study the transmission prop-erties of light through generalized Thue-Morse (GTM (m, n))aperiodic superlattices and obtain the formulae of the transmission coefficients (TCs) analytically at the central wavelength, which are confirmed by numerical simula-tions. It is found that: (1) all of the lst generation systems are transparent to the substrates medium B; (2) GTM(m, 2j) systems are transparent to the substrates medium B; (3) GTM (2i, 2j+1) systems are translucent to the sub-strates medium B except the lst generation; and (4) when i≠j, transmission through GTM (2i+1, 2j+l) systems attenuates rapidly with the increase of generation number I and sequence parameters m, n. On the other hand, the po-sitional correlations between the constituents of GTM (m, n) aperiodic superlattices responsible for the resonant states are also discussed. Based on the conclusions we study the properties of the amplitude of the electric field vector and find that they are different from those of periodic lattices and chaotic systems.
