A completely covariant approach to transformation optics
We show that the Plebanski based approach to transformation optics overlooks some subtleties in the electrodynamics of moving dielectrics that restricts its applicability to a certain class of transformations. An alternative, completely covariant, approach is developed that is more generally applicable and provides a clearer picture of transformation optics.
متن کاملHiding an elephant into a matchbox with transformation optics
Based on transformation optics, we propose an illusion device that can make objects look much smaller and different than they actually are. In particular, the device has a capability to hide a large object (like an elephant) into a small one (like a matchbox). Compared to previous proposals for illusion devices, there is no requirement for negative refractive index or for spee...
متن کاملTransformation Optics Approach to Plasmon-Exciton Strong Coupling in Nanocavities.
We investigate the conditions yielding plasmon-exciton strong coupling at the single emitter level in the gap between two metal nanoparticles. Inspired by transformation optics ideas, a quasianalytical approach is developed that makes possible a thorough exploration of this hybrid system incorporating the full richness of its plasmonic spectrum. This allows us to reveal that by placing the emit...
متن کاملComplex coordinates in transformation optics
We show that complex coordinates used in conjunction with transformation optics offer an extra degree of freedom that allows control over not only the propagation direction of electromagnetic waves but also their amplitude. We illustrate this idea in two applications. First, we show that in an n-dimensional space one can manipulate the field amplitude for up to n different amplitude distributio...
متن کاملRecent advances in transformation optics.
Within the past a few years, transformation optics has emerged as a new research area, since it provides a general methodology and design tool for manipulating electromagnetic waves in a prescribed manner. Using transformation optics, researchers have demonstrated a host of striking phenomena and devices; many of which were only thought possible in science fiction. In this paper, we review the ...
