- Abstract:
- In order to investigate the effect of correlation on Anderson localization in electromagnetic waves,a random one-dimensional binary waveguide array is proposed based on a random binary sequence,and a quasi-periodic one-dimensional binary waveguide array is proposed based on a Fibonacci sequence.The transition,localization length and the spectra of the electrical field amplitude of tranverse electric(TE)mode for the two one-dimensional binary waveguide arrays are calculated using transfer matrix method.Experiments are carried out using one-dimensional rectangular microwaves waveguide structure.The peaks of transmission spectrum of the random one-dimensional binary waveguide array proposed based on a random binary sequence are identical with those of periodic waveguide arrays,the modes near the band edges become localized; the propagation characteristics of the quasi-periodic one-dimensional binary waveguide array proposed based on a Fibonacci sequence is independent of its basic unit, and electromagnetic energy is transferred discretely through the coupling between the spatial distributed localizations.
