High Absorption and Second-Harmonic Generation in Split Ring Resonator Multilayer Nanostructure

Figure 7

The absorption spectra of (a) fundamental frequency field 𝐸_𝑥⁽¹⁾, (b) second-harmonic field 𝐸_𝑥⁽²⁾, and (c) second-harmonic field 𝐸_𝑦⁽²⁾ are calculated for the wide 𝑑=210 nm, while maintaining other structure parameters the same as the design in Figure 2.
