Review of Black Hole Realization in Laboratory Base on Transformation Optics (Invited Paper)

Abstract

Abstract-Realizations of celestial objects in the laboratory have been a tantalizing subject for human beings over centuries. In this paper, we review some of the interesting cases of realizations of black holes in the laboratory. We first review the recent progress in observed black holes realized through the isotropic coordinate transformation method, then discuss the realization of optical attractors. Finally, the Rindler space-time, as a one-dimensional black hole, by using the hyperbolic metamaterials, is discussed.

Boundary integral equation method for resonances in gradient index cavities designed by conformal transformation optics

“…Recently, transformation optics (TO) has been attracting great interest because it provides the theoretical basis of incredible optical gear such as optical invisibility cloak [1][2][3][4] and realization of celestial objects such as optical black holes in laboratory [5]. Also, beyond optics it is widely applicable to acoustic waves [6,7], elastic waves [8,9], and seismic waves [10], etc.…”

Transformation Optics: From Classic Theory and Applications to its New Branches

“…geometrical optics, wave diffusion theory, Fourier optics, etc.) have been designed and even experimentally demonstrated with TO, including an invisibility cloak, [20,[26][27][28][29][30][31][32] wave concentrators, [33,34] rotators, [35][36][37][38] beam splitters, [39,40] compressors, [41] perfect lenses, [42][43][44] illusion optical devices, [45,46] PEC reshapers, [47,48] superscatterers, [49][50][51][52] optical black holes, [53][54][55] optical wormholes, [56,57] wavefront modulators, [58,59] waveguide devices, [60][61][62] and antenna radiation controllers, [63][64][65] etc. Among these works, there are some notable experimental milestones, such as the realizations of an invisibility cloak in the microwave band, [27,28] infrared band [29] and visiblelight band, [32] electromagnetic wave rotators for microwave…”

Double layered transformation cavities: Crossover between local and global transformations

“…Consequently, TO has become a powerful tool to control the propagation of electromagnetic waves [5][6][7]. Many novel optical devices and unprecedented applications have been demonstrated with TO, including individual cloaks [2,[8][9][10], wave concentrators [11,12], optical black holes [13][14][15], waveguide devices [16][17][18], and negative refractive index materials [19][20][21].…”
