DOI: 10.1016/j.ijthermalsci.2021.107225

Abstract: Abstract The mid-infrared spectral range is critical for bio-sensing and gas detection. Existing methods for designing wavelength-selective absorbers involve two-dimensional (2D) and three-dimensional (3D) nanofabrication, which is exceedingly expensive, rendering these methods impracticable. The application… read more here.

DOI: 10.1364/ao.415461

Abstract: A dual-band terahertz metamaterial narrowband absorber is investigated based on a single simple windmill-shaped structure. The proposed metamaterial absorber achieves near-perfect absorption at 0.371 THz and 0.464 THz. The full width at half-maximum is 0.76%… read more here.

Published in 2023 at "Optics express"

DOI: 10.1364/oe.488336

Abstract: This paper proposes a switchable broadband/narrowband absorber based on a hybrid metasurface comprising graphene and metal in the millimeter-wave regime. The designed absorber achieves broadband absorption when the surface resistivity of graphene Rs = 450… read more here.
