“…Yet, fabrication complexity and the requirement for precise temperature and voltage control pose challenges. Moreover in [20], an active broadband perfect absorber MM based on hexagonal-patterned VO2 is proposed, achieving adjustable absorption within the 6.5 to 7.90 THz range. Yet, it exhibits a low modulation depth and requires a high operating temperature.…”

This paper presents a groundbreaking advancement in terahertz (THz) technology through the introduction of a novel ultrathin absorber. Composed of vanadium dioxide (VO 2 ) and graphene, this absorber offers a non-metallic solution for wideband absorption, covering an impressive frequency range from 1.198 THz to 8.752 THz (7.554 THz). Our absorber exhibits exceptional tunable and switchable performance, a significant achievement considering the challenge of achieving frequency tunability across broadband absorption ranges, which was the primary focus of our research endeavor. Furthermore, our proposed absorber demonstrates remarkable characteristics, achieving up to 80% absorption even at high incidence angles of up to 80 o . Additionally, the absorber enhances Shielding Effectiveness in electromagnetic interference (EMI) shields and stealth systems, further highlighting its versatility and potential impact in various applications.INDEX TERMS Absorber, graphene, switchable, tunable, VO 2 , Wideband.
