We investigate the classical traversability of an analogue spatial wormhole geometry realized on a two-dimensional curved carbon membrane. The background is obtained by implementing a reflection-symmetric doubling technique on the exterior spatial sector of a non-rotating Bañados-Teitelboim-Zanelli black hole, effectively replacing the event horizon with a smooth traversable throat. Within this framework, massless Dirac quasiparticles propagate as spinorial light rays whose kinematics are governed exclusively by the metric curvature, forcing them to track the null geodesics of the ultrastatic spacetime. By evaluating the exact geodesic equations, we demonstrate that classical traversability is dictated by a sharp binary threshold in the conserved angular momentum, where the minimum throat radius acts as a centrifugal potential barrier that separates traversing paths from reflecting ones. We show that near-critical trajectories experience a logarithmic divergence in their angular evolution, causing the quasiparticles to execute multiple spatial windings around the throat before escaping. These classical ray-tracing configurations establish the necessary geometric backbones for future mesoscopic investigations.
