“…These aperiodic structures can be generated by deterministic rules and posses long-range order [16]. Unlike periodic structure, aperiodic deterministic structures lack both translational and rotational symmetries but present scale invariance symmetry (self-similarity) in their spectral and structural structure [17]. Fibonacci multilayers is an example of aperiodic system with discrete Fourier spectrum characterized by self-similar bragg peaks which determine the location and width of the frequency band-gap [18,19].…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
