Many physical properties of our universe, such as the relative
strength of the fundamental interactions, the value of the
cosmological constant, etc., appear to be fine-tuned for existence
of human life. One possible explanation of this fine tuning assumes
existence of a multiverse, which consists of a very large number of
individual universes having different physical properties.
Intelligent observers populate only a small subset of these
universes, which are fine-tuned for life. In this book we will
review several interesting metamaterial systems, which capture many
features of important cosmological models and offer insights into
the physics of many other non-trivial spacetime geometries, such as
microscopic black holes, closed time-like curves (CTCs) and the
Alcubierre warp drive.
Hyperbolic metamaterials were originally introduced to overcome the
diffraction limit of optical imaging. Soon thereafter it was
realized that hyperbolic metamaterials demonstrate a number of
novel phenomena resulting from the broadband singular behavior of
their density of photonic states. These novel phenomena and
applications include super resolution imaging, new stealth
technologies, enhanced quantum-electrodynamic effects, thermal
hyperconductivity, superconductivity, and interesting gravitation
theory analogs. Here I review typical material systems, which
exhibit hyperbolic behavior and outline important new applications
of hyperbolic metamaterials, such as imaging experiments with
plasmonic hyperbolic metamaterials and novel VCSEL geometries, in
which the Bragg mirrors may be engineered in such a way that they
exhibit hyperbolic properties in the long wavelength infrared
range, so that they may be used to efficiently remove excess heat
from the laser cavity. I will also discuss potential applications
of self-assembled photonic hypercrystals. This system bypasses 3D
nanofabrication issues, which typically limit hyperbolic
metamaterial applications. Photonic hypercrystals combine the most
interesting features of hyperbolic metamaterials and photonic
crystals.
