“…There are many studies in the literature on optical structures, such as metamaterials and photonic crystals (Sung et al, 2011;Alipour-Banaei et al, 2017;Chen et al, 2017;Zhang et al, 2018;Benhaddad et al, 2019;Napolskii et al, 2020;Shi et al, 2020;Singer et al, 2020). Phononic structures affected by sound waves also show structurally similar properties to photonic crystals among optical structures (Lu et al, 2017;Sun et al, 2019;Ayman et al, 2020;Rostami et al, 2020;Trzaskowska et al, 2020;Rostami et al, 2021).…”

In this study, electromagnetic wave propagation frequencies are investigated in four different photonic crystal structures, three of which are tripartite and one of which is bipartite. In addition, the effects of part lengths and material property parameters (ε, µ) of these structures on electromagnetic wave frequencies are examined. The photonic crystal structures are one-dimensional (1D) and the parts of these structures have different lengths. Differences in the part lengths allow the electromagnetic wave frequencies to be adjusted. The material property parameters of each part of the photonic crystal structures change in the x-axis direction and the default values of these parameters theoretically change from 1 to 2. The values for the first three modes of electromagnetic wave frequencies obtained for four different photonic crystal structures are different from each other. The lowest values of the electromagnetic wave frequencies are obtained for the first photonic crystal structure (S1) with the shortest first and second part lengths.

“…One notable characteristic of phononic crystals is their ability to impede the passage of acoustic or elastic waves within the bandgap region. This unique property of phononic crystals has led to numerous applications in engineering, including guiding [1][2][3], ltering [4][5][6][7][8], switching [9], sensing [10], and demultiplexing [11]. As a result, extensive research has been conducted on phononic crystals over the past two decades.…”

This study presents a novel approach to achieve a controllable demultiplexer by applying a magnetic field in a solid-solid phononic crystal structure. The proposed phononic crystal structure consists of a square lattice made of tungsten cylinders embedded in a PMMA substrate. The switchable demultiplexer is composed of two identical but symmetrical parts, with an input waveguide separating them. Each unit comprises an output channel and a common input channel, with output channels side-coupled by a ring resonator to the input bus waveguide. The operating frequency range of the demultiplexer is in the MHz regime. The switchability of this elastic demultiplexer is achieved by dynamically controlling Young's modulus. By applying a magnetic field to the structure, the Young's modulus of the Terfenol-D material used in the output waveguide is altered, allowing for controllability. The proposed demultiplexer demonstrates an average crosstalk value of -12.65 dB, indicating suitable performance, along with a high average quality factor (Q) of 1870. The solid-solid elastic structure is simulated using the finite element method.
