Lateral Shift Makes a Ground-Plane Cloak Detectable
TL;DR: The effectiveness of the ground-plane invisibility cloak generated from quasiconformal mapping of electromagnetic space is examined, which shows that, for a bump with a maximum height of 0.2 units to be hidden, the lateral shift of a ray with 45° incidence is around 0.15 units.
