Modeling electrical dispersion phenomena in Earth materials

Annals of Geophysics, 2008
It is illustrated that IP phenomena in rocks can be described using conductivity dispersion models deduced as solutions to a 2nd-order linear differential equation describing the motion of a charged particle immersed in an external electrical field. Five

Polarization properties of interferometrically interrogated fiber Bragg grating and tandem-interferometer strain sensors [PDF]

, 2006
Lead sensitivity in low-coherence interferometric fiber-optic sensors is a well-known problem. It can lead to a severe degradation in the sensor resolution and accuracy through its effect on the fringe visibility and interferometric phase.

Polarization-Induced Interaction as a Perturbation within Orbital Angular Momentum(OAM) Modes of an Optical Fiber

, 2021
We investigate the role of polarization effects in orbital angular momentum modes of an optical fiber. Specifically, we revisit the removal of the degeneracy of the $HE$ and the $EH$ vector modes that exists within the weakly guiding approximation (WGA);

Identification of induced polarization of submarine hydrocarbons in marine controllable source electromagnetic exploration

Frontiers in Earth Science, 2023
The identification of hydrocarbons buried on the seafloor is highly dependent on geophysical exploration capabilities. Seismic exploration has been an important tool in providing information on submarine stratigraphy before offshore drilling, but it is a
