The absorption band occurs at two resonance frequencies: 0.1 GHz and 0.14 GHz. The bandwidth is determined by the frequency width at half maximum (FWHM). The resulting quality factor (Q = f/FWHM, where f represents the resonance frequency) ranges between 32.6 and 34.04. Additionally, owing to its symmetrical geometry, the absorber demonstrates polarization insensitivity under normal incidence. Consequently, the designed effective absorber holds promise for applications as a sensor and electromagnetic detector for GHz frequencies.
