| Popis: | We study the band structure and the transmission coefficient properties of electromagnetic waves in one-dimensional quasi-periodic Fibonacci structure. Our structure is composed of periodic waveguides in which the resonators having different lengths and depend on each other following a Fibonacci sequence grafted onto N equidistant sites. This study shows that comb-like structures of the Fibonacci type can exhibit localized bands with higher amplitude in the transmission spectrum. The variation between the resonator lengths give rise to new created gaps in the passbands, called flat bands. This structure can be used in the electromagnetic telecommunications field, in the design of new filter, multichannel and even for multiplexing and other engineering devices. |
