Plasmons in nearly touching metallic nanoparticles: singular response in the limit of touching dimers.
The response of gold nanoparticle dimers is studied theoretically near and beyond the limit where the particles are touching. As the particles approach each other, a dominant dipole feature is observed that is pushed into the infrared due to interparticle coupling and that is associated with a large pileup of induced charge in the interparticle gap. The redshift becomes singular as the particle...
متن کاملTouching geometry
Geometric models and algorithms have been traditionally designed to support graphics, visualization, and spatial reasoning. Recent developments in human computer interfaces are now making it possible to \touch" virtual geometric objects | we can feel interaction forces with haptic interfaces and hear realistic contact sounds with auditory displays. These interfaces pose new challenges for the d...
متن کاملTemperature limit values for touching cold surfaces with the fingertip.
OBJECTIVES At the request of the European Commission and in the framework of the European Machinery Directive, research was performed in five different laboratories to develop specifications for surface temperature limit values for the short-term accidental touching of the fingertip with cold surfaces. METHODS Data were collected in four laboratories with a total of 20 males and 20 females pe...
متن کاملTouching the Physical World
I would like to propose going beyond the tactile experience and extend the tangibility to other senses. Imagine a way to interact with an information environment and explore multiple layers of time and space. Spatial exploration is immersive and multidimensional. So, instead of using only a finger as input, the full body acts as pivot point to produce augmented realities, blending the cyberspac...
متن کاملQuantum optical response of metallic nanoparticles and dimers.
The optical properties of metallic nanoparticles (NPs) can be described with analytical models based on fundamental quantum mechanical principles, of which the Drude model constitutes the classical limit. Here, we examine the plasmonic properties of silver and gold nanospheres and dimers, with radii ranging from 10 to 1 nm, extending from the classically described regime to the quantum size reg...
