The purpose of this study is development a novel high-performance low-Petahertz (PHz) biosensor for non-melanoma skin cancer (NMSC) diagnosis. presented device designed to work within microwave imaging regime, which promising alternative conventional diagnostic methods such as visual examination, dermoscopy, and biopsy. suggested incorporates dual-band perfect absorber (operating bands at 0.909 PHz 1.215 PHz) constructed using aluminum layers separated by dielectric material. Numerical studies confirm its suitability NMSC diagnosis, enabling discrimination between healthy cancerous tissues precise visualization affected areas. Compared existing THz devices, the proposed offers improved sensitivity, smaller size, enhanced resolution, attributed partially transition petahertz band. Moreover, our research highlights potential spectroscopy biomarker detection, advancing non-invasive techniques other cancers. boasts higher figure merit (FOM), quality factor (Q-factor), while insensitivity polarization angle ensures superior signal-to-noise ratio high-resolution imaging, instilling confidence in specialists.

Cervical cancer belongs to the most dangerous types of cancers posing considerable threat women’s survival. It is often diagnosed in advanced stages as precancerous lesions are symptom-free and difficult identify. Microwave imaging, especially terahertz (THz) range, a convenient noninvasive detection tool. enables characterization biological tissues discrimination between healthy malignant ones. This study presents novel triple-band biosensor based on metamaterials (MTMs). By leveraging unique properties MTMs, proposed operates perfect absorber. exploits resonant modes THz spectrum achieve remarkable sensitivity. Meticulous selection sensor geometry dimensions efficient miniaturization. Meanwhile, utilization frequency-domain data detect refractive index changes improves resolution cancerous tissue identification. Extensive numerical investigations corroborate its ability carry out reliable early-stage cervical diagnosis. includes identification spatial extent tissue. Excellent electrical accompanied by compact size, which highly desirable for non-invasive portable applications.

This paper proposed a compact, high-sensitive S-band microwave sensor for low permittivity characterization. The is inspired by metamaterials-based maze-shaped split-ring resonator (MS-SRR) configuration, and its overall dimensions are 25 mm × 20 0.79 mm. unloaded state of the achieved two robust band-stop notches in transmission response at 2.77 GHz 3.08 GHz, respectively. These distinctive features enable simultaneous measurement low-permittivity materials. MS-SRR configuration accomplished strong electric-field intensity, which increased interaction between field testing material, resulting highly sensitive measurement. A sensitivity 11.91% observed first resonance peak 12.01% second within range from 1 to 2.0. Moreover, also competent measuring 3 10 with 9.47%–4.93% 9.57%–4.83% peak. frequency shifting influence material under test (MUT) presented as function using regression model. simulated, measured formulated results agree well. Finally, compact holds promise characterization applications.
