Using the Green’s tensor area integral equation method and reflection spectroscopy, resonant light scattering from rectangular gold nanostrips on quartz substrates fabricated with electron-beam lithography is analyzed theoretically and demonstrated experimentally. Theory and experiments are compared and found in a good agreement. Design curves presenting the scattering resonance wavelength as a function of the nanostrip width allow one, by carefully choosing the strip width and thickness, to realize the resonance at a given wavelength in a broad wavelength spectrum ranging from the visible to the near infrared including telecommunication wavelengths .
