Abstract:We investigate the spatial and temporal localization properties of quasimodes (i.e. scattering resonances) of two-dimensional Vogel spirals, composed of deterministic, aperiodic arrays of electric dipoles. By determining the structural entropy and localization maps of Vogel spirals using the Green's matrix method, we show that three distinctive decay types of quasimodes coexist in Vogel spirals: exponential, power-law, and gaussian. While the former has been expected to occur in disordered media only, the latt… Show more
