We show that a hybrid metamaterial slab comprising of an one-dimensional array of two different types of cavities exhibits ferrimagnetic-like surface resonances which can be used to realize interesting phenomena such as directive emission as a consequence of strong angle-dependent reflection phase and the selective coupling of a Gaussian incident beam into a higher order diffractive channel, giving rise to the phenomenon of negative reflection and retro-directive backtracking. The findings are verified by experiments in the microwave regime.
