Dispersion equations are obtained and the conditions of existence are considered for surface electromagnetic waves in quasiperiodic dielectric superlattices with layers arranged according to the recurrent Fibonacci rule. It is shown that in the quasiperiodic superlattices an immense number of surface modes exists approximately proportional to the number of layers in the structure. Excitation of surface waves is studied in quasiperiodic superlattices using attenuated total reflection (ATR) technique. Angular and frequency dependences of reflection coefficient for ATR technique are of fractal character.
