Plasmonic Bandgaps in 1D Arrays of Slits on Metal Layers Excited by Out-of-Plane Sources

Figure 10

Magnetic field component 𝐻_𝑧 at λ = 611.23 nm of the equivalent system with the parameters in Figure 9 applied to the case of θ = 10°. Exploiting the even symmetry of the structure, the left side of the magnetic field is the mirrored replica of this plot. Red arrows indicate the direction of the Poynting vector. In this case the source has a Gaussian-shaped spatial profile.
