Reactor vibration reduction based on giant magnetostrictive materials

open access: yesAIP Advances, 2017
The vibration of reactors not only produces noise pollution, but also affects the safe operation of reactors. Giant magnetostrictive materials can generate huge expansion and shrinkage deformation in a magnetic field.

Influence of Mutual Coupling on Stability of RCS Response in Chipless RFID

open access: yesTechnologies, 2018
The paper investigates the influence of mutual coupling between individual scatterings of chipless Radio Frequency Identification (RFID) tags based on its frequency-domain performance using a simplified equivalent circuit model. The proposed steady state

The Enlightened Game of Life [PDF]

open access: yes, 2010
We investigate a special class of cellular automata (CA) evolving in a environment filled by an electromagnetic wave. The rules of the Conway's Game of Life are modified to account for the ability to retrieve life-sustenance from the field energy.

On the m-CAP Performance with Different Pulse Shaping Filters Parameters for Visible Light Communications

open access: yesIEEE Photonics Journal, 2017
In pulse shaping filters, parameters such as the roll-off factor and the symbol span, which determine the overall performance, are of great importance when implementing a real-time system due to limited hardware resources.

Electromagnetic Force on a Brane

open access: yes, 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.
