Simulated Study of a Broadband Terahertz Metamaterial Absorber Based on Vanadium Dioxide Resonator for Cancer Detection Applications
Popis výsledku v původním jazyce
This paper presents a broadband terahertz (THz) metamaterial absorber (MTMA) utilizing vanadium dioxide (VO2) for cancer detection applications. The proposed absorber incorporates closed circular ring resonators (CCRR) on its top layer, achieving a wide absorption range from 0.8 to 2.19 THz with a bandwidth of 1.22 THz and two distinct absorption peaks exceeding 99% at 0.97 THz and 2.1 THz. Benefiting from the phase transition property of the VO2, the absorber offers switchable performance, making it suitable for various sensing scenarios. The dual-band absorption peaks shift with changes in the refractive index of the surrounding medium, with a minimum sensitivity value ranging from 3.75 THz/RIU to a maximum of 24.16 THz/RIU. The absorber's performance was validated by detecting six types of human cancer cells, including skin, blood, breast, adrenal glands, cervical, and tongue cancers, through frequency variations. These results demonstrate the potential of the proposed absorber for advancing THz-based healthcare telemetry devices and cancer detection technologies.
