Fake black holes in the lab would emit Hawking radiation just like real ones.

In a paper published in Physical Review Letters, Dartmouth researchers proposed a new way of creating a reproduction black hole in the laboratory on a much smaller scale than their celestial counterparts.

A magnetic field-pulsed microwave transmission line containing an array of superconducting quantum interference devices, or SQUIDs reproduces physics analogous to that of a radiating black hole.

In principle, this setup enables the exploration of analogue quantum gravitational effects and the study of Hawking radiation.
