The technique of "transformation optics" establishes a correspondence between coordinate transformation and material constitutive parameters. Most of the transformation optics mappings give metamaterials that have graded positive refractive indices that can steer light in curves defined by the coordinate transformation.

Optical Illusions Recognition Intelligence
IEEE Symposium on Wireless Technology and ApplicationsOptical illusions have intrigued humanity for centuries, challenging our perception and understanding of visual stimuli. This paper delves into the realm of optical illusions through the lens of image processing techniques.

Nature, 1914
I HAVE often noticed the phenomenon mentioned by Mr. J. W. Giltay in NATURE of April 23 (p. 189). In the position in which he was reading the sunlight passed through his eyelids and the coats of his eyes, and on account of having to pass through a layer of blood which acted as a red screen his retinas become flooded with red light.

Analysis of Smoothed LHE Methods for Processing Images with Optical Illusions
Visual Communications and Image Processing, 2018To replicate human visual perception, we analyze processing images with optical illusion using edge preserving filters and smoothed local histogram equalization (LHE).

A New Optical-Geometrical Illusion
Perception, 2007We describe and attempt to explain a new and unusual optical-geometrical illusion with three levels of distortion. The illusory figure is made up of three juxtaposed bands of the same width, which, when appropriately juxtaposed, appear to be of different widths. We hypothesised that the effect would depend on the combined action of various factors: (i)

Another Optical—Geometrical Illusion
Perception, 1978A new optical—geometrical illusion is described. The parallelism of short rows of dots is affected by some unknown factor, so that the rows appear as pivoting on their middle point. Some explanations of the illusion are considered, but with no success.
