Positioning and Mitigating Mining-Induced Phase Gradients for InSAR Phase Unwrapping

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Interferometric synthetic aperture radar (SAR) has been widely used for deformation monitoring in mining areas. However, the nonlinear high-phase gradients caused by subsidence funnels are a major source of error in accurate measurements, as they present

Controlling the light diffraction through a single subwavelength metallic slit via phase gradient

New Journal of Physics, 2023
In this work, we show that the concept of phase gradient metasurfaces provides a versatile way to control the diffraction of light through small holes or slits.

Refined Coseismic Slip Model and Surface Deformation of the 2021 Maduo Earthquake: Implications for Sensitivity of Rupture Behaviors to Geometric Complexity

Remote Sensing
Geometric complexities of a fault system have a significant impact on the rupture behavior of the fault. The 2021 Mw7.4 Maduo earthquake occurred on a multi-segmented complex sinistral fault in the interior of the Bayan-Har block in the northern Tibetan ...

Multi-Beam Metasurface Antenna by Combining Phase Gradients and Coding Sequences

IEEE Access, 2019
In this paper, we propose a strategy to achieve a single-feed multi-beam metasurface antenna by combining phase gradient and coding sequence. Theoretically, the multi-beam antennas with various far-field patterns can be realized via superimposing ...

Whey proteins eluted reversed phase gradients

Journal of High Resolution Chromatography, 1997
AbstractThe behavior of bovine whey proteins in Reversed‐Phase High Performance Liquid Chromatography (RP‐HPLC) systems has been investigated. The Linear Solvent Strength (LSS) model has been applied to the separation of these proteins studying how their retention time and band broadening change when different gradient parameters are modified. From our

Spontaneous PT symmetry breaking of a ferromagnetic superfluid in a gradient field

, 2015
We consider the interaction of a ferromagnetic spinor Bose-Einstein condensate with a magnetic field gradient. The magnetic field gradient realizes a spin-position coupling that explicitly breaks time-reversal symmetry T and space parity P, but preserves

Magnetic properties of dense holographic QCD [PDF]

, 2009
We investigate the Sakai-Sugimoto model at nonzero baryon chemical potential in a background magnetic field both in the confined phase and in the deconfined phase with restored chiral symmetry. In this case the 8-brane Chern-Simons term becomes important.

An Ultra-Wideband Reflective Phase Gradient Metasurface Using Pancharatnam-Berry Phase

IEEE Access, 2019
Designing a transmissive and reflective phase gradient metasurface (PGM) using Pancharatnam-Berry (PB) geometrical phase must be based on an appropriate metasurface, which can realize circular-polarization (CP)-conversion transmission and CP-maintaining ...

Phase synchronization analysis by assessment of the phase difference gradient

Chaos: An Interdisciplinary Journal of Nonlinear Science, 2009
Phase synchronization is an important phenomenon of nonlinear dynamics and has recently received much scientific attention. In this work a method for identifying phase synchronization epochs is described which focuses on estimating the gradient of segments of the generalized phase differences between phase slips in an experimental time series. In phase

Studies of Phase Turbulence in the One Dimensional Complex Ginzburg-Landau Equation

, 1996
The phase-turbulent (PT) regime for the one dimensional complex Ginzburg-Landau equation (CGLE) is carefully studied, in the limit of large systems and long integration times, using an efficient new integration scheme.
