We study of the optical properties of U shaped resonators made of gold synthesized by e-beam lithography. One electric-like resonant mode near 990 nm and one magnetic-like resonant mode near 885 nm are characterized. We show that the influence of magneto-electric coupling can be separated from that of spatial dispersion by performing measurements along the optic axes of the resonators. Our model provides a comprehensive description of the optical properties of U-shaped resonators in visible domain.
