Smart windows are emerging as an effective way of minimizing energy consumption in buildings. They attracted the major relevance for minimizing energy consumption in buildings. More research studies are needed to design smart windows with operating wide range and don’t require additional energy to operate. We suggest a novel smart window structure using photonic crystal to regulate the solar radiation intensity by preventing it from penetrating the buildings in summer. For the first time, the suggested smart window photonic crystal at room temperature is proposed. The suggested smart window can block about 400 nm of near-infrared. This smart window model doesn’t require additional heat or electric input to operate.

The rise of broadband cellular networks and 5G networks enable new rates of data transfer. This paper introduces a new design to measure the permittivity in the GHz range of non-magnetic materials. We tested the proposed design with a wide range of materials such as wood, glass, dry concrete, and limestone. The newly proposed design structure has a maximum sensitivity of 0.496 GHz/RIU. Moreover, it can measure permittivities in the range from 1 up to 9. The main component of the designed structure is a defective one-dimensional photonic crystal with a unit cell consisting of metamaterial and silicon. In addition, we demonstrate the role of the metamaterial in enhancing the proposed design and examine the impact of the defect layer thickness on the proposed structure.

“…In the last few decades, 1D, 2D, and 3D photonic crystals (PCs) and phononic crystals have been received extensive attention in sensing applications as a biochemical sensor, salinity sensor, and filters (El-Khozondar et al 2019 ; Arafa et al 2017 ; Beheiry et al 2010 ; Natesan et al 2018 ; Arunkumar et al 2019 ; Amiri et al 2019 ; Elsayed and Mehaney 2018 ; Zaky et al 2020 ; Abd El-Ghany et al 2020 ; Zaky and Aly 2020 ; Khateib et al 2020 ). The PCs are periodic structures of alternating dielectrics (Abd El-Ghany et al 2020 ; Aly and Elsayed 2012 ; Aly et al 2020a ; Aghajamali et al 2015 ; Nayak et al 2017 , 2018 , 2019 ; Guo et al 2020a ; Srivastava and A. J. J. O. S. Aghajamali, and N. Magnetism 2017 ; Shiri et al 2019 ; Zhou et al 2021 ), nanocomposites (Aly et al 2018a ), superconductors (Aly et al 2019 , 2018b ), or metal with different refractive indices in one, two or three directions (Yablonovitch 1987 ; Shaban et al 2017 ; Winn et al 1998 ). There is a forbidden region for a specific range of wavelengths in a propagated electromagnetic wave.…”

The performance of one-dimensional photonic crystal for plasma cell application is studied theoretically. The geometry of the structure can detect the change in the refractive index of the plasma cells in a sample that infiltrated through the defect layer. We have obtained a variation on the resonant peak positions using the analyte defect layer with different refractive indices. The defect peak of the optimized structure is red-shifted from 2195 to 2322 nm when the refractive index of the defect layer changes from 1.3246 to 1.3634. This indicates a high sensitivity of the device (S = 3300 nm/RIU) as well as a high Q-factor (Q = 10 3 ). The proposed sensor has a great potential for biosensing applications and the detection of convalescent plasma.
