Query: Boyer-Lindquist space-times and beyond: Meta-material analogues   Physically reasonable stationary axisymmetric spacetimes can (under very mild
technical conditions) be put into Boyer-Lindquist form. Unfortunately a metric
presented in Boyer-Lindquist form is not well-adapted to the "quasi-Cartesian"
meta-material analysis we developed in our previous article on "bespoke
analogue spacetimes" (arXiv:1801.05549 [gr-qc]). In the current article we
first focus specifically on spacetime metrics presented in Boyer-Lindquist
form, and determine the equivalent meta-material susceptibility tensors in a
laboratory setting. We then turn to analyzing generic stationary spacetimes,
again determining the equivalent meta-material susceptibility tensors. While
the background laboratory metric is always taken to be Riemann-flat, we now
allow for arbitrary curvilinear coordinate systems. Finally, we reconsider
static spherically symmetric spacetimes, but now in general spherical polar
rather than quasi-Cartesian coordinates. The article provides a set of general
tools for mimicking various interesting spacetimes by using non-trivial
susceptibility tensors in general laboratory settings.
