Abstract:	The results of the propagation of electromagnetic waves in 1D periodic photonic waveguides and resonators are presented in this study. This structure consists of periodically arranged cells, with each cell containing parallel and series segments, grafted by two resonators at two different sites. This system creates passbands separated by photonic bandgaps, in which electromagnetic waves cannot propagate. The analytical calculation is based on the transfer matrix method (TMM), which aims to calculate the dispersion relation and transmission rate. Our results indicate the importance of the resonator length in applications, such as guiding and filtering electromagnetic waves. This study also demonstrates how the addition of cells and the adjustment of resonator lengths influence the frequency selectivity, which is essential for filtering in communication technologies.
