Modelling electromagnetic responses of 2-D structures due to spatially non-uniform inducing fields. Analysis of magnetotelluric source effects at coastlines
(Wiley Blackwell Publishing, Inc, 2003-10)
In previous works, we presented 2-D and 3-D magnetotelluric modelling methods based on Rayleigh-Fourier expansions. These methods are an alternative to finite-element and finite-difference techniques and are especially ...
The use of pulsed electric acoustic technique for measuring electric field profiles in ferroelectric ceramic
(2002-12-01)
The pulsed electric acoustic technique, PEA, have been usually applied to probe space charge profiles in polymers. In this work we show preliminary results obtained with lead zirconate-titanate and niobium, PZTN, ferroelectric ...

Lightning Induced Voltages on Overhead Lines above Non-Uniform and Non-Homogeneous Ground
(2014-11)
Abstract: lightning induced voltages are one of the most common sources of failures on distribution networks operating in high lightning activity regions. Traditionally, the selection of insulation levels and protecting ...
Coupling time-lapse ground penetrating radar surveys and infiltration experiments to characterize two types of non-uniform flow
(2022-02-01)
Understanding linkages between heterogeneous soil structures and non-uniform flow is fundamental for interpreting infiltration processes and improving hydrological simulations. Here, we utilized ground-penetrating radar ...
Dissipative structures induced by spin-transfer torques in nanopillars
(American Physical Society, 2014)
Macroscopic magnetic systems subjected to external forcing exhibit complex spatiotemporal behaviors as
result of dissipative self-organization. Pattern formation from a uniform magnetization state, induced by the
combination ...
Fingerprints of a position-dependent Fermi velocity on scanning tunnelling spectra of strained graphene
(IOP Publishing Ltd, 2018)
Nonuniform strain in graphene induces a position dependence of the Fermi velocity, as recently demonstrated by scanning tunnelling spectroscopy experiments. In this work, we study the effects of a position-dependent Fermi ...
