Summary: In this study, a novel high-performance metamaterial absorber with ultra-broadband high absorption and polarization selectivity in the entire long-wavelength infrared (LWIR) atmospheric window is proposed. The absorber exhibits an absorptance higher than 90% with a 4750 nm bandwidth and precise polarization-selective absorption. It provides a promising approach to simplify LWIR imaging and detection systems and further improve their performance, with remarkable spectral stability when the geometric parameters of the microstructure change.

Summary: This paper proposes an ultra-broadband absorber with high absorption in the long-wave infrared regime. By utilizing a second-order Peano fractal curve metasurface, the absorber achieves enhanced absorption through the generation of multiple gap plasmon resonance modes. The findings provide general strategies for designing metamaterial absorbers with excellent broadband absorption.

Summary: We propose an ultra-thin perfect absorber consisting of a periodic Ti trapezoidal pyramid array, GaAs dielectric spacer layer, and Ti reflection substrate, achieving high absorption in the long-wave infrared band. The average absorptivity of 93.6% in the 8-15μm band is obtained, insensitive to polarization angle and incidence angle, due to the excitation of propagating surface plasmon resonance and local surface plasmon resonance. The resonance characteristics and broadband absorption properties were analyzed using electrostatic theory and multipole decomposition method.

Summary: This paper presents an interesting scheme of an ultra-broadband perfect terahertz (THz) absorber using a periodic-conductivity graphene metasurface. By modulating the conductivity of graphene in a periodic manner, the absorber can generate dense high-order resonance modes and achieve ultra-broadband continuous absorption. This scheme is significant for the development of broadband THz absorbers and has promising application prospects in THz stealth, imaging, and communication fields.
