The relationship between the spatial structure and the transport properties of these modes is studied analytically in terms of the transmission and Lyapunov coefficients. Power spectrum analysis of the critical modes indicates a complex modulated structure in agreement with previous experimental results, [S0163-1829(99)11337-7]. eng open access Physical nature of critical modes in Fibonacci quasicrystals journal article
