This study delves into the design and analysis of plasmonic absorbers utilizing Metal-Insulator-Metal (MIM) ring resonator devices to achieve heightened optical absorption efficiency. Various ring resonator topologies, namely SRR-L and Ring-L, are investigated with the objective of amplifying absorption capabilities. Moreover, the examination extends to the influence of modifying the inner radius of the ring, resulting in discernibly diverse absorption levels. Through the integration of these ring resonators, absorption peaks are effectively brought into proximity, thereby yielding a broad-band absorption spectrum. Our discoveries underscore the promising potential of these devices as proficient optical detectors. The simulations were performed in three dimensions utilizing CST Microwave Studio.
