This paper addresses the discrepancy between the idealized planar view of collisionless fast-magnetosonic shocks and the observed corrugated structure. It proposes a linear-MHD model to understand how upstream turbulence drives this corrugation. The key innovation is treating the shock as a moving interface, allowing for a practical mapping from upstream turbulence to shock surface deformation. This has implications for understanding particle injection and radiation in astrophysical environments like heliospheric and supernova remnant shocks.
