Abstract
We report on the possibility of modulating the transport properties of crit ical normal modes in Fibonacci quasicrystals by using the mass ratio as a t uning parameter. The relationship between the spatial structure and the tra nsport properties of these modes is studied analytically in terms of the tr ansmission and Lyapunov coefficients. Power spectrum analysis of the critic al modes indicates a complex modulated structure in agreement with previous experimental results, [S0163-1829(99)11337-7].
