The dipole and quadrupole localized surface plasmon resonances were directly investigated by a near-field scanning optical microscope. Results manifest the correlation of the oblique incident polarizations and the responded higher order plasmon resonances under 488-nm and 633-nm laser excitations in the vicinity of gold nanoparticles.
