The role of the surface waves at ultra high field imaging is investigated for a loop coil and a dipole antenna. Loop coil represents a magnetic dipole, which is placed vertically and horizontally along B0 direction while the dipole antenna represents the electric dipole placed on a dielectric half-space. Surface waves measured in the water substrate which is placed on a EG gel phantom at 7 T MRI. They may lead to a larger lateral FOV of an RF coil then expected.
