Magic Carpet: Interaction Fidelity for Flying in VR

IEEE Transactions on Visualization and Computer Graphics, 2020
Locomotion in virtual environments is currently a difficult and unnatural task to perform. Normally, researchers tend to devise ground- or floor-based metaphors to constrain the degrees of freedom (DoFs) during motion.

Tunable arc-shaped acoustic metasurface carpet cloak

Smart materials and structures (Print), 2020
In this paper, a tunable arc-shaped acoustic metasurface (AAM) carpet cloak has been proposed and systematically investigated. The AAM carpet cloak consists of covers, rotors, bolts and nuts.

A 3D Carpet Cloak with Non‐Euclidean Metasurfaces

Advanced Optical Materials, 2020
Metasurfaces have opened up a new era of manipulating electromagnetic waves including the implementation of invisibility cloaks, based on their simple design and ultrathin thickness. However, a perfect design of metasurface structures, such as the carpet

Topology-optimized thermal carpet cloak expressed by an immersed-boundary level-set method via a covariance matrix adaptation evolution strategy

International Journal of Heat and Mass Transfer, 2019
Our proposal, a topology optimization method for thermal carpet cloaks, eliminates the disturbance caused by a bump obstacle on a flat boundary and, despite the presence of the bump, reproduces the temperature distribution as if no bump is present ...

Experimental demonstration of irregular thermal carpet cloaks with natural bulk material

International Journal of Heat and Mass Transfer, 2019
Invisibility carpet cloak has been typically captivated as a popular notion that can render the objects beneath invisible from detection. Previous attempts either forcefully remove the small anisotropy caused by quasi-conformal mapping or resort to ...

Formation of ozone-initiated VOCs and secondary organic aerosol following application of a carpet deodorizer

, 2020
Volatile Organic Compounds (VOCs) emission and Secondary Organic Aerosols (SOA) formation from a water-based carpet deodorizer were investigated in a 20 m3 walk-in climate chamber with and without a textile carpet installed.

Experimental Demonstration of a 3D‐Printed Arched Metasurface Carpet Cloak

Advanced Optical Materials, 2019
Metasurfaces have an extraordinary wavefront manipulation capability to generate various functionalities with ultrathin planar structures and provide an unprecedented means of easily achieving invisibility carpet cloaks in practice.
