Abstract

Meeting the increasing demand for cost-effective Metamaterial (MTM) devices poses a challenge, particularly in creating a straightforward and polarization-independent interfacial water heating device due to the nanoscale dimensions involved. Our proposed solution addresses this challenge through uncomplicated designs, incorporating basic geometric shapes as MTM inclusions to form metal-insulator-metal combinations and periodically arranged metal-insulator layers. By employing high-loss materials such as Nickel and Tungsten as metal inclusions, we have successfully demonstrated substantial Electromagnetic (EM) wave absorption within the 400 nm to 1600 nm range, achieving over 80 percent absorption across the visible to infrared spectrum. Additionally, we introduced liquid crystal layers to the Metal-Insulator-Metal (MIM) structure, providing tunability and expanding the device's usability across a wider range of the EM spectrum. Regarding fabrication and optimization for mass production, these designs have the potential to serve as valuable additions to interfacial heating devices.
