disappearance of plasmonically induced reflectance by breaking symmetry in metamaterials

Although, using cut-out i-ii and h-ii structures, it has been proved that symmetry broken is necessitous to have a plasmonically induced reflectance (pir) but it is also possible to create pir effect in a symmetric cut-out h-ii structure. in this paper, in addition to reaffirming the possibility of creating pir effect in symmetric structure using i-ii structure, it is also proved, for both the i-ii and h-ii structures, that the created pir effect in symmetric case can be vanished by breaking the symmetry. the created pir effect in the two i-ii and h-ii structures will be compared in different situations.
