Nevertheless, MRI is more sensitive to metals than radiography, and metallic artifacts caused by metallic fillings, such as crowns or inlays often appear in the oral maxillofacial region, complicating diagnosis.
However, MRI is sensitive to metals, and numerous types of metallic appliances, most of which have a large magnetic susceptibility, are used in orthodontic treatment and may cause severe artifacts on MRI.
The shape of the G− component is highly sensitive to whether the SWNT is metallic, where a broad structure of the G− band appears, or semiconducting (single-component G− band) [5].
This fact strongly suggests that the PL intensities in the Si ND arrays are enhanced by plasmonic effects induced by the Au nanostructures because plasmon-enhanced local electric fields of lights are known to be highly sensitive to the edge shape of metallic nanostructures.
The metallic mesh is very sensitive to a change of the refractive index of materials attached to the metallic mesh.
Meanwhile, the frequency of LSP is sensitive to the shape and size of metallic nanostructures as well as the dielectric constant of the surrounding material.
The ID/IG′ ratio is suggested for evaluation of the defects in carbon nanotubes samples since it is less sensitive to doping both for semiconducting and metallic tubes.
On the other hand, the effect of local field enhancement is observed in these materials, which is sensitive to the dielectric environment of the metallic nanoparticles, and can be used for the amplification of light at the nanoscale [9].
Sandwich structures with metallic foam core are sensitive to local indentation because of the low strength of the core and low bending stiffness of the thin face sheets.
Impulsive stimulated light scattering (ISLS) has been developed to enable measurements on metallic samples but is sensitive to surface properties, and data analysis is relatively complex (e.g. Crowhurst et al., 2006).
