Illusion Media: Generating Virtual Objects Using Realizable Metamaterials

open access: yes, 2010
We propose a class of optical transformation media, illusion media, which render the enclosed object invisible and generate one or more virtual objects as desired.

Ray-optical negative refraction and pseudoscopic imaging with Dove-prism arrays [PDF]

open access: yes, 2008
A sheet consisting of an array of small, aligned Dove prisms can locally (on the scale of the width of the prisms) invert one component of the ray direction.

Cloaking and imaging at the same time

open access: yes, 2012
In this letter, we propose a conceptual device to perform subwavelength imaging with positive refraction. The key to this proposal is that a drain is no longer a must for some cases.

Rectangularity Is Stronger Than Symmetry in Interpreting 2D Pictures as 3D Objects

open access: yesFrontiers in Human Neuroscience, 2022
It is known that the human brain has a strong preference for rectangularity in interpreting pictures as 3D shapes. Symmetry is also considered to be a factor that the human vision system places high priority on when perceiving 3D objects.

Magnetic illusion: transforming a magnetic object into another object by negative permeability

open access: yes, 2018
We theoretically predict and experimentally verify the illusion of transforming the magnetic signature of a 3D object into that of another arbitrary object.

State anxiety influences P300 and P600 event-related potentials over parietal regions in the hollow-mask illusion experiment

open access: yesPersonality Neuroscience, 2021
The hollow-mask illusion is an optical illusion where a concave face is perceived as convex. It has been demonstrated that individuals with schizophrenia and anxiety are less susceptible to the illusion than controls. Previous research has shown that the

Reduced sensitivity to visual looming inflates the risk posed by speeding vehicles when children try to cross the road [PDF]

open access: yes, 2011
Almost all locomotor animals respond to visual looming or to discrete changes in optical size. The need to detect and process looming remains critically important for humans in everyday life.

"Positive space (A new perspective for the application of the optical illusion art in advertising design)"

open access: yesJournal of Architecture, Art & Humanistic Science, 2020
The Optical Art, known as Op-Art, is one of the artistic movements that emerged in the late twentieth century. It is characterized by a purely visual relationship between the recipient and the artistic work. It aims to change the visual perception of the
