“…Multilayer materials have been extensively researched for application in heat-shielding windows in buildings, [10,11,14,48,[55][56][57] and the same principles can be adapted for thermal management in greenhouses as well. Some of the earliest multilayer systems for NIR blocking involved alternating metal and dielectric layers, [58] which can make for high costs of depositions on large surfaces like greenhouse covers.…”

Greenhouse horticulture grows increasingly important due to its ability to provide a controlled microclimate which is optimizable for highly efficient crop growth and resource use, although it may come at a significant energy and investment cost. One of the most crucial inputs in any greenhouse is sunlight, giving free energy and light for greenhouse crop growth. However, it is enormously variable, both geographically and seasonally. This review discusses materials and technologies usable in greenhouse cover and screen materials which can passively manipulate the incident sunlight to transmit a light spectrum that is ideal for crop growth, thereby improving the yield, and for greenhouse microclimate management, thereby reducing the energy usage of greenhouses. The current status of spectrum‐manipulating technology in greenhouses, developments over the last few years, some potential innovations adaptable from diverse fields to greenhouse horticulture, and the associated challenges, are discussed.

“…The Helmholtz equation investigates the propagation of the acoustic wave within the proposed sensor structure as 2 : where c L is the longitudinal speed of the acoustic wave through the tub, and P is the acoustic pressure. TMM is a standard method for studying the transmission and reflection of the incident acoustic and optic waves with multitube structures [29][30][31][32][33][34] . The following matrix describes the interplay between the proposed system and acoustic waves.…”

Here, we investigate a gas sensor model based on phononic crystals of alternating tubes using the transfer matrix method to detect hazardous greenhouse gases. The effect of the thicknesses and cross-sections of all tubes on the performance of the proposed sensor is studied. The results show that longitudinal acoustic speed is a pivotal parameter rather than the mass density variations of the gas samples on the position of the resonant peaks due to its significant impact on the propagation of the acoustic wave. The suggested sensor can be considered very simple and low-cost because it does not need a complicated process to deposit multilayers of different mechanical properties’ materials.
