Multilayer reflective boundaries used to guide and resonate light impart reflective phase shifts that depend on both angle of incidence and polarization. In cavities, these phase shifts can have a large effect on the spatial and polarization patterns of the eigenmodes, creating completely new structures. Here I discuss two new families of modes found in simple dome-shaped cavities. Both families owe their existence to derivatives of the boundary phase shift with respect to incident angle.
