  While quantum field theory could more aptly be called the "quantum field
framework" $-$ as it encompasses a vast variety of varying concepts and
theories $-$ in comparison, relativity, both special and general, is more
commonly portrayed as less of a "general framework". Viewed from this
perspective, the paradigm of "analogue space-times" is to promote the specific
theory of general relativity (Einstein gravity) to a framework which covers
relativistic phenomena at large. Ultimately, this then also gives rise to new
proposals for experiments in the laboratory, as it allows one to move general
features of the "relativistic framework" from general relativity to entirely
new fields. This allows experiments looking into analogies of currently
unobservable phenomena of general relativity proper. The only requirement for
this to work is the presence of a notion of an upper limit for propagation
speeds in this new field. Systems of such a kind abound in physics, as all
hyperbolic wave equations fulfil this requirement.
  Consequently, models for analogue space-times can be found aplenty. We shall
demonstrate this here in two separate analogue space-time models, both taken
from electrodynamics in continuous media. First of all, one can distinguish
between analytic analogue models (where the analogy is based on some specific
hyperbolic differential equation), on the one hand, and algebraic models (where
the analogy is fashioned from the more or less explicit appearance of a metric
tensor), on the other hand. Yet this distinction is more than just a matter of
taste: The analogue space-time model's nature will also determine which
physical concepts from general relativity can be taken easily into an
experimental context. Examples of this will the main aim of this paper, and the
Hawking effect in one of the two models considered the example of most
immediate experimental interest.
