The propagation paths of oceanic internal tides are influenced by their interactions with vortices. We examine the scattering effect that an isolated vortex in (cyclo)geostrophic balance has on a rotating shallow-water plane wave. We run a suite of simulations in which we vary the non-dimensional vorticity of the vortex, $Ro$, the relative scale of the vortex size to the Rossby radius of deformation, $Bu$, and the size of the vortex compared to the plane wave wavelength, $K$. We compare the scattered wave flux pattern to ray-tracing predictions. Ray tracing predictions are relatively insensitive to $K$ in the $10.2$, it plateaus following a sigmoid
