“…Moreover, quasiperiodic photonic crystals inspired by mathematical sequences, such as the Fibonacci (S n = S n−1 + S n−2 ) [14,15], Thue-Morse (S n+1 = S n Sn , Sn+1 = Sn S n ) and double-period [16][17][18], Octonacci (S n = S n−1 S n−2 S n−1 , for n ⩾ 3) [19,20], and Dodecanacci sequences (S n = {AS n−2 S n−1 } 2 S n−1 , for n ⩾ 3) [21][22][23][24][25], have also been explored. These sequences, known for their recursive nature, further contribute to the versatility of quasiperiodic photonic crystals.…”

Quasiperiodic magnonic crystals, in contrast to their periodic counterparts,lack strict periodicity which gives rise to complex and localised spin wave spectracharacterized by numerous band gaps and fractal features. Despite their intrinsicstructural complexity, quasiperiodic nature of these magnonic crystals enables bettertunability of spin wave spectra over their periodic counterparts and therefore holdspromise for the applications in reprogrammable magnonic devices. In this article, weprovide an overview of magnetization reversal and precessional magnetization dynamicsstudied so far in various quasiperiodic magnonic crystals, illustrating how theirquasiperiodic nature gives rise to tailored band structure, enabling unparalleled controlover spin waves. The review is concluded by highlighting the possible potentialapplications of these quasiperiodic magnonic crystals, exploring potential avenues forfuture exploration followed by a brief summary.
