We study the light scattering and surface plasmon resonances of Au nanorods that are commonly used as optical nanoantennas in analogy to dipole radio antennas for chemical and biodetection field-enhanced spectroscopies and scanned-probe microscopies. With the use of the boundary element method, we calculate the nanorod near-field and far-field response to show how the nanorod shape and dimensio...

Surface plasmon resonance sensors (SPR) using copper for sensitive parts are a competitive alternative to gold and silver. Copper oxide is semiconductor has non-toxic nature. The unavoidable presence of may be interest as it non-toxic, but modifies the condition performance sensor. Therefore, characterization optical properties thin films interest. We propose method recover both thicknesses fro...
