Boundary element method for surface nonlinear optics of nanoparticles
We present the frequency-domain boundary element formulation for solving surface second-harmonic generation from nanoparticles of virtually arbitrary shape and material. We use the Rao-Wilton-Glisson basis functions and ...
Video Conferencing in the Age of Covid-19 : Engaging Online Interaction Using Facial Expression Recognition and Supplementary Haptic Cues
More than 50 years since its mass market introduction the core user interfaces of Video Conferencing (VC) systems have essentially been unchanged. Relay-ing real time audio and video over distance is inherently productive. ...
End-User Attitudes towards Location-Based Services and Future Mobile Wireless Devices: The Students' Perspective
Nowadays, location-enabled mobile phones are becoming more and more widespread. Various players in the mobile business forecast that, in the future, a significant part of total wireless revenue will come from Location-Based ...
Use of microcutting for high throughput electrode patterning on a flexible substrate
The use of printing technologies is promising for low-cost manufacturing of flexible, light-weight and large-area electronics, such as electronic paper or solar cells. Here, we demonstrate a microcutting technique and ...
Te incorporation and activation as n-type dopant in self-catalyzed GaAs nanowires
Dopant atoms can be incorporated into nanowires either via the vapor-liquid-solid mechanism through the catalyst droplet or by the vapor-solid growth on the sidewalls. Si is a typical n-type dopant for GaAs, but in nanowires ...
Interference system for high pressure environment
Laser interference patterning or lithography has been used in variety of the applications using, patterning, masking and processing structures at top of material. It offers fast processing over as large areas can be processed ...
Modes and resonances of plasmonic scatterers
We present a rigorous full-wave electromagnetic approach to analyze the modes and resonances of dielectric and plasmonic nanoparticles of practically any geometry. Using boundary integral operators, we identify the resonances ...
