Liquid Crystals into Planar Photonic Crystals

One-Dimensional Photonic Crystals With the Superconducting Defects

“…The PBGs are forbidden regions in the dispersion law and in transmittivity spectra, where EMWs with selected frequencies cannot propagate through the PC. A lot of attention has been directed to the study of conventional PCs on the base of dielectrics, semiconductors, and normal metals as well as on the base of functional materials like magnetics [7,8], ferroelectrics [9,10] and liquid crystals [6,11,12] which can be controlled by external magnetic or electric fields. Another interesting group of PCs are those with superconducting (SC) constituents, socalled superconducting PCs.…”

The Phase Morphology of 2,5 DI-Substituted Pyridine Derivatives: A Quantum Mechanical Analysis

“…Mesogens are very sensitive to the external parameters, and this sensitivity makes them useful in various applications such as display devices, photonic crystals, sensors, and biomedical applications [2][3][4]. Thermotropic liquid crystals can be categorized as nematic, cholesteric, and smectic [5].…”
