We study the guided modes in a wire medium (WM) slab, taking into account the nonlocality and losses in the structure. We show that due to the fact that the WM is an extremely spatially dispersive metamaterial, the effect of nonlocality plays a critical role, since it results in coupling between the otherwise orthogonal guided modes. We observe the effects of strong and weak coupling, depending on the level of losses in the system.
