(a) The comparison of E field versus frequency curves with the notched. The red solid line represents the presence of a cell, while the black dotted line represents the absence of a cell, both within a structure of identical dimensions. (b) E-field strength distribution with cell and notch with a 1 V/m single-frequency continuous wave excitation source. (c) Cumulative histogram of E field within the beam. The green solid line denotes the resonator without notches, whereas the brown dotted line represents the resonator with notches, both having the same structural dimensions and cell
