چکیده
This research focuses on the analysis of a metal-dielectric-metal structured metamaterial absorber aimed at achieving resonant absorption with an ultra-narrow spectral bandwidth in the mid-infrared region. The initial evaluation of the structure’s electromagnetic response was carried out through full-wave electromagnetic simulations using CST Studio Suite. To enhance the design efficiency, an equivalent circuit model was developed, enabling the extraction of effective structural parameters and rapid evaluation of its resonant behavior. A parametric sensitivity analysis based on this model quantitatively determined the influence of geometric variables on key absorption characteristics, including the resonance wavelength location, peak absorption, and Full Width at Half Maximum. Optimization results indicate that this absorber is capable of achieving perfect absorption with a very narrow bandwidth; for instance, at the resonant wavelength of , an absorption of approximately 99.99% with a bandwidth of about was observed. The demonstrated narrowband absorption characteristics make this metamaterial absorber a promising platform for future infrared spectroscopy applications, including bio-chemical sensing systems.
