Higher-order topological insulators are a recently discovered class of materials that can
possess zero-dimensional localized states regardless of the dimension of the system. Here …

Biosensor technology is a quite attractive and rapidly developing research field in recent
years, and the sub field of optical photonic crystal (PC) biosensor based on label free …

Photonic crystals have shown an interesting performance as chemical, biochemical and
biological sensors. The proposed chemical sensor is based on a ternary photonic crystal …

Several research efforts have been devoted to exploring defect modes of uniform phononic
crystals (PnCs) with single or double defects. However, they have difficulties in achieving …

Phononic crystals (PnCs) have received growing attention in recent years, due to their ability
to manipulate elastic waves, such as in the case of defect-mode-enabled energy …

Mesostructured materials can exhibit enhanced light–matter interactions, which can become
particularly strong when the characteristic dimensions of the structure are similar to or …

We show that point defects in two-dimensional photonic crystals can support bound states in
the continuum (BICs). The mechanism of confinement is a symmetry mismatch between the …

Reciprocal space engineering allows tailoring the scattering response of media with a low
refractive‐index contrast. Here it is shown that a quasiperiodic leveled‐wave structure with …

This work introduces the recent so called Bravais–Moiré theory in the context of two
dimensional photonic crystals. In particular, new periodic cells involving commensurable …

Photonic crystals can be adopted to control light propagation due to their superior band gap
feature. It is well known the band gap feature of photonic crystals depends significantly on …
