Unusual modes and photonic gaps in a Vicsek waveguide network
Sheelan Sengupta, Arunava Chakrabarti
We propose a simple model of a waveguide network designed following the growth rule of a Vicsek fractal. We show, within the framework of real space renormalization group (RSRG) me…

Wave propagation in a quasi-periodic waveguide network
Sheelan Sengupta, Arunava Chakrabarti
We investigate the transport properties of a classical wave propagating through a quasi-periodic Fibonacci array of waveguide segments in the form of loops. The formulation is gene…

Electronic transport in a Cantor stub waveguide network
Sheelan Sengupta, Arunava Chakrabarti, Samar Chattopadhyay
We investigate theoretically, the character of electronic eigenstates and transmission properties of a one dimensional array of stubs with Cantor geometry. Within the framework of…
