The extinction spectra of the proposed trimer (a) for varying position of right nanorod g₁ at d₁ = d₂ = 2 nm and g₂ = 0 and (b) for varying length of left nanorod L₃ at d₁ = d₂ = 2 nm and g₁ = g₂ = 0. The electric field distributions at resonant peaks (c) P₁, (d) P₂, and (e) P₃, for L₃ = 170 nm, respectively. All the other structure parameters of the trimer are the same as those in Fig. 6.
