Abstract Research into tunable broadband absorbers has recently grown in popularity due to the terahertz technology’s spectacular development. This article proposes and analyzes a metamaterial structure based on vanadium dioxide (VO 2 ) that can be used as absorber, which is tuned dynamically. The upper layer of absorber made VO , ground composed gold, middle dielectric substrate polyimide. prescribed design provides more than 95 % absorption with 4 THz bandwidth from 3.3 7.3 THz. Moreover, peak intensity constantly enhanced 5 97 when ’s conductivity varies 200 × 10 S/m. transition enables dynamic control between high reflection states. research endeavours thoroughly investigate -based Metamaterial Absorber (MMA), encompassing all aspects validation modelling using an electronic equivalent lumped design. conductive phenomena radiating patch achieve percentage for relevant frequency band very useful understand. Additionally, it been verified polarization angle no effect absorptance. potential applications including imaging, sensing, detection, electromagnetic cloaking, optoelectronic switches.
