“…Consequently, plasma photonic crystals (PPCs) have attracted increased research interest in the case of one-, two-and threedimensional systems [3,[10][11][12][13]. Thus far, the PPCs have been used to achieve tunable photonic bandgaps (PBGs) [3,14,15] and introduce peaks in the bandgap [16,17]. Recently, Gao et al demonstrated a structural tunable PPC in a dielectric barrier discharge by self-organization of the plasma filaments.…”

We propose a Fano switch arising from the superlattice array of a plasma-filled quartz tube, which can be tuned and reconfigured by the plasma density in the tube. The generation of the switch depends on a Fano band that is induced by the interference between the Mie resonance in an isolated cylinder and Bragg scattering in a periodic array. The underlying dispersion characteristics reveal that a localized tunable flat band corresponding to the Mie resonance plays an important role in the appearance of the Fano resonance. This active tunable switch can be potentially applied to microwave communications as a single-pole multi-throw switch and to monitor environmental variables that impact the plasma density.

“…The resulting structures were called function photonic crystals. With these, the concept of conventional photonic crystals is extended a step further: so-called "function dielectrics" enable rapid control of material properties, e.g., the electro-optical Kerr effect [22] or the magneto-optical Faraday effect [23], in a highly tailored and customizable manner [24][25][26][27][28][29][30][31].…”

We propose a novel type of phononic crystal for which the materials parameters are continuous functions of space coordinates without discontinuities corresponding to a seamless fusion of the constituent materials within the crystal lattice. With help of an adaptation of this fundamental approach, we extend the well-established concept of phononic crystals, allowing an investigation of the transition from a conventional phononic crystals with a regulated step-like parameter function to the realm of so-called function phononic crystals. Our study is based on a first-principle theory assisted by high-performance computer simulations and focuses on an understanding of the effects of a deviation from the typical parameter step function on the phononic density of states (DOS).  Our exploration of the DOS reveals a characteristic rapid convergence: even a slight deviation from an ideal step function has the potential to induce radical changes in the band structure leading to the emergence of desirable features, especially multiple complete phononic band gaps.
