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 ...

The Structure of an Electromagnetic Field [PDF]

Proceedings of the National Academy of Sciences, 1918
This elementary field corresponds to a state of affairs in which electric charges of a concentrated form are created and travel along straight lines with the velocity of light, the directions of these lines being specified by the different values of the unit vector s.

Coupling Theory of Emergent Spin Electromagnetic Field and Electromagnetic Field [PDF]

Journal of the Physical Society of Japan, 2014
In ferromagnetic metals, an effective electromagnetic field which couples to conduction electron spin is induced by the sd exchange interaction. We investigate how this effective field, spin electromagnetic field, interacts with the ordinary electromagnetic field by deriving an effective Hamiltonian based on the path-integral formalism.

Power module heat sink design optimization with ensembles of data-driven polynomial chaos surrogate models

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 ...

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

Phantom Pain Reduction by Non-ionizing Electromagnetic Treatment [PDF]

, 2010
Based on our years of experience testing a technique called non-ionizing Electromagnetic-Own-Signal-Treatment (EMOST), here, we present our preliminary results for phantom pain reduction by this method under clinical circumstances.
