Abstract The frequency mixing property of time-modulated metasurfaces, attributed to the well-known phenomenon temporal photonic transition, has led several exotic functionalities in last lustrum. Based on this concept, we demonstrate possibility achieving nonreciprocal responses near-infrared regime via combining a platform and static high-Q metasurface. In particular, metasurface is designed ...

In the present paper a novel structure for optical channel drop filter (CDF) based on photonic crystal ring resonator with circular core has been proposed. In order to design the proposed CDF, the plan wave expansion (PWE) method is applied for calculation of band structure and photonic band gap while the transmission characteristics of proposed CDF have been calculated using the finite differe...

In this manuscript, density functional theory was used to explore structural, vibrational and optical properties of the (Sc2O3)n (n=1-5) cluster systems using DFT/B3LYP/LanL2DZ level of computation. Different stable isomers were obtained and numerous chemical parameters such as HOMO-LUMO gap, ionization potential and electron affinity were calculated successfully. Stability of the clusters was ...
