Media and Communications*

, 2018
Developments in digital technologies over the last 30 years have expanded massively human beings’ capacity to communicate across time and space (Section 13.1). Media infrastructures have simultaneously acquired huge complexity. By “media” we mean technologies for the production, dissemination, and reception of communication, but also the contents ...

Localization of Human Cortical Areas Underlying Glossiness Perception: An fMRI Study

i-Perception, 2011
We conducted two fMRI experiments to clarify what cortical areas are involved in perception of surface glossiness. To dissociate activations caused by glossiness from those caused by low-level features such as luminance and luminance contrast of the ...

Impedance-Modulating Patch Integration for Gain and Bandwidth Control of Antenna-in-Display in Millimeter-Wave Smartphones [PDF]

Journal of Electromagnetic Engineering and Science
In this study, an impedance-modulating patch (IMP) antenna-in-display (AiD) scheme is introduced to enable on-demand modification of the antenna operating frequency, bandwidth, and gain by selectively laminating a film with a printed IMP onto a pre ...

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, EarlyView.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

All‐Optical Reconfigurable Physical Unclonable Function for Sustainable Security

Advanced Materials, EarlyView.
An all‐optical reconfigurable physical unclonable function (PUF) is demonstrated using plasmonic coupling–induced sintering of optically trapped gold nanoparticles, where Brownian motion serves as a robust entropy source. The resulting optical PUF exhibits high encoding density, strong resistance to modeling attacks, and practical authentication ...
