Constraints of Using Conductive Screen-Printing for Chipless RFID Tags with Enhanced RCS Response
Applied Sciences, 2022 The analysis and experimental verification of the properties of four types of chipless RFID tags with an increased RCS response level designed and fabricated by conductive screen-printing using silver paste on foil and paper substrates was performed. The

ELECTROMAGNETIC FIELDS ON FRACTALS [PDF]
Modern Physics Letters A, 2006 Fractals are measurable metric sets with non-integer Hausdorff dimensions. If electric and magnetic fields are defined on fractal and do not exist outside of fractal in Euclidean space, then we can use the fractional generalization of the integral Maxwell equations. The fractional integrals are considered as approximations of integrals on fractals. We

Sleep EEG-Based Approach to Detect Mild Cognitive Impairment
Frontiers in Aging Neuroscience, 2022 Mild Cognitive Impairment (MCI) is an early stage of dementia, which may lead to Alzheimer’s disease (AD) in older adults. Therefore, early detection of MCI and implementation of treatment and intervention can effectively slow down or even inhibit the ...

Controlling Electromagnetic Fields
Science, 2006 Using the freedom of design that metamaterials provide, we show how electromagnetic fields can be redirected at will and propose a design strategy. The conserved fields—electric displacement field D , magnetic induction field B , and Poynting vector B —are all ...

High frequency characterization of Galfenol minor flux density loops
AIP Advances, 2017 This paper presents the first measurement of ring-shaped Galfenol’s high frequency-dependent minor flux density loops. The frequencies of applied AC magnetic field are 1k, 5k, 10k, 50k, 100k, 200k, 300k, 500 kHz. The measurements show that the cycle area

On rational electromagnetic fields [PDF]
Physics Letters A, 2020 We employ a recently developed method for constructing rational electromagnetic field configurations in Minkowski space to investigate several properties of these source-free finite-action Maxwell ("knot") solutions. The construction takes place on the Penrose diagram but uses features of de Sitter space, in particular its isometry group. This admits a

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