Variation in the absorption amplitude for the different resonator conditions of the proposed absorber structure. The absorption spectrum for the computational wavelength spectrum for (a) Design M1 and (b) Design M2 for the unit cell size. (c) Design M1 (b) Design M2 for single horizontal, single vertical and L-shaped modes. (e) Design M1 (f) Design M2 for the different values of the resonator length (L), changing from 300 nm to 450 nm for the computational condition with the consideration of Ag as the resonator material.
