Light in Memristive Atomic Scale Junction - Memristors go Photonics [PDF]
EPJ Web of Conferences, 2023 Memristive devices are an emerging new type of devices operating at the scale of a few or even single atoms. They largely exploited for emulating the electrical function of synapses and are thus currently investigated for performing in-memory and ...

Accelerated sources in de Sitter spacetime and the insufficiency of retarded fields [PDF]
, 2001 The scalar and electromagnetic fields produced by the geodesic and uniformly accelerated discrete charges in de Sitter spacetime are constructed by employing the conformal relation between de Sitter and Minkowski space.

Waveguide coupled III-V photodiodes monolithically integrated on Si
Nature Communications, 2022 To realize on-chip optical communication schemes based on silicon, the integration of waveguides onto III-V devices must be achieved. Here, the authors report waveguide-coupled III-V heterostructure photodiodes monolithically integrated on silicon ...

e-Prime: Advances in Electrical Engineering, Electronics and Energy, 2022 We consider the problem of optimizing the design of a heat sink used for cooling an insulated gate bipolar transistor (IGBT) power module. The thermal behavior of the heat sink is originally estimated using a high-fidelity computational fluid dynamics ...

Electromagnetic Force on a Brane
, 2016 A fundamental assumption in the theory of brane world is that all matter and radiation are confined on the four-dimensional brane and only gravitons can propagate in the five-dimensional bulk spacetime.

Transformation media that rotate electromagnetic fields [PDF]
, 2007 We suggest a way to manipulate electromagnetic wave by introducing a rotation mapping of coordinates that can be realized by a specific transformation of permittivity and permeability of a shell surrounding an enclosed domain. Inside the enclosed domain,

Eddy current testing of metallic sheets with defects using force measurements [PDF]
Serbian Journal of Electrical Engineering, 2008 The problem of determining defects in structures using eddy current methods was investigated. The goal of this work is to demonstrate that the forces generated by the eddy currents and acting back on the magnet system can be used to detect defects in the
