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

A comparision of Hodgkin-Huxley and soliton neural theories [PDF]

open access: yesAdvances in Radio Science, 2010
Hodgkin and Huxley were the pioneers to abstract biological neuron as an electric circuit and nerve signal as the voltage impulse. The Hodgkin-Huxley theory (Hodgkin and Huxley, 1952) has set the direction and defined the goals for much of the ensuing ...

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.

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.
