Neural computer using electromagnetic coupling

Systems and Computers in Japan, 1992
AbstractA neural computer is referred to as a connectionism or an ultraparallel distributed processing system, compared to a conventional computer. However, it is necessary to develop an effective wire connecting method among neurons to realize a large‐scale network involving a huge number of neurons.This paper proposes a new neural computer ...

Electromagnetics and coupled problems

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 2000
Introduces the fourth and final chapter of the ISEF 1999 Proceedings by stating electric and magnetic fields are influenced, in a reciprocal way, by thermal and mechanical fields. Looks at the coupling of fields in a device or a system as a prescribed effect.

Electromagnetic Coupling and Shielding

1995
The role, effects, and function of electromagnetic coupling are among the most important topics in cable shielding. They are also among the most confusing and challenging issues. The existing approaches span two extremes: (1) reducing all the shielding mechanisms to different forms of coupling, and (2) ignoring completely the role of coupling in ...

Electromagnetic coupling of twisted pair cables

IEEE Journal on Selected Areas in Communications, 2002
Increasing deployment of digital subscriber line (DSL) technology operating in the long wave, medium wave and sometimes short wave frequency ranges, has raised the question of how such systems interact with rival radio frequency sources and equipment. Two of the major standards bodies in the field, ITU and ETSI, imposed by the standardization of such ...

A Coupled Electromagnetic and Mechanical Analysis of Electromagnetic Acoustic Transducers

International Journal for Computational Methods in Engineering Science and Mechanics, 2009
In this paper a comprehensive finite element analysis of Electromagnetic Acoustic Transducer (EMAT) is presented. The analysis has been performed using complete and incomplete expressions for excitation current and results have been compared with published data to assess the accuracy of the complete expression approach.

Coupling to Electromagnetic Fields

2011
Electromagnetism is the most important interaction for the study of atoms, molecules and materials. It determines most of the potentials or perturbation operators V which are studied in practical applications of quantum mechanics, and it also serves as a basic example for the implementation of other, more complicated interactions in quantum mechanics ...

Coupling of Stochastic Electromagnetic Beams into Optical Fibers

Frontiers in Optics 2009/Laser Science XXV/Fall 2009 OSA Optics & Photonics Technical Digest, 2009
We derive a general analytic expression for the coupling efficiency when a partially coherent, partially polarized beam is coupled into a multimode optical fiber. We adopt the Gaussian-Schell model for incident electromagnetic beams and use our general result to discuss the effects of the partial coherence and partial polarization on the coupling ...

Other Electromagnetic Couplings

1995
In this chapter we are concerned with other electrodynamic theories which show new features, not present in four-dimensional spinor QED. The new feature in scalar QED is the derivative coupling between the scalar field and the vector potential. It has important consequences for gauge invariance, in particular, the interaction gets modified by gauge ...

Electromagnetic field couplings

2019
With the continuous shrinkage of the minimum feature sizes of semiconductor integrated circuits and their packages along with the increase in the operating frequency have caused parasitic electromagnetic (EM) coupling to become a serious design concern.

Noncontact Monitoring of Cardiorespiratory Activity by Electromagnetic Coupling

IEEE Transactions on Biomedical Engineering, 2013
In this paper, the method of noncontact monitoring of cardiorespiratory activity by electromagnetic coupling with human tissue is investigated. Two measurement modalities were joined: an inductive coupling sensor based on magnetic eddy current induction and a capacitive coupling sensor based on displacement current induction.
