Polariton Electric-Field Sensor [PDF]
Physical Review Letters, 2020 We experimentally demonstrate a dipolar polariton based electric field sensor. We tune and optimize the sensitivity of the sensor by varying the dipole moment of polaritons. We show polariton interactions play an important role in determining the conditions for optimal electric field sensing, and achieve a sensitivity of 0.12 V-m$^{-1}$-Hz$^{-0.5 ...

Polychromatic electric field knots [PDF]
Physical Review Research, 2021 The polarization of a monochromatic optical beam lies in a plane, and in general, is described by an ellipse, known as the polarization ellipse. The polarization ellipse in the tight focusing (non-paraxial) regime forms non-trivial three-dimensional topologies, such as M bius and ribbon strips, as well as knots.

Electric field measurement in electric-field modified flames
Proceedings of the Combustion Institute, 2021 Abstract The application of an electric field to a flame modifies the flame characteristics due to the collective motion of charged particles generated within the flame. The applied field mobilises electrons and ions depending on their polarity, leading to localised regions of space charge with sufficient density to either locally amplify or shield ...

Electrically silent magnetic fields
Biophysical Journal, 1986 There has been a significant controversy over the past decade regarding the relative information content of bioelectric and biomagnetic signals. In this paper we present a new, theoretical example of an electrically-silent magnetic field, based on a bidomain model of a cylindrical strand of tissue generalized to include off-diagonal components in the ...

Electric fields and electrical insulation [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2002 The adoption of a field-theoretical approach to problems arising in the framework of electrical insulation is discussed with reference to six main topics, which have been addressed over the last 30 years. These include uniform field electrodes, Green's differential equation, electrode surface roughness, induced charge, electrostatic probes, and partial

Electric field-assisted biosorption
Biotechnology Letters, 2004A bisorption process using electric fields to facilitate contact between a sorbate and non-living biomass is described. The latter is enclosed within a semi-permeable membrane together with an electrode. The counter electrode is placed in the sorbate solution and an established potential across the electrodes facilitates electrokinetic movement of the ...

Electric Field Reversal in Sprite Electric Field Signature
Monthly Weather Review, 2013Abstract In measurements of the electric field associated with the current of a sprite 450 km from ground-based field sensors, it was observed that the sign of the electric field was positive when positive charge was lowered from the ionosphere.

Electric field gradient focusing
Journal of Separation Science, 2005AbstractElectric field gradient focusing (EFGF) is a relatively new separation technique with promising attributes, particularly for protein analysis. The fundamental fractionation mechanism in EFGF involves a gradient in electric field along the length of a separation column.

Electric‐Field‐Driven Deracemization
ChemPhysChem, 2006AbstractWe demonstrate, both theoretically and experimentally, that it is possible to use an electric field to drive the formation of macroscopic chiral (conglomerate) domains from an initially homogeneous fluid racemate. Field‐induced segregation is exhibited in a fluid smectic liquid‐crystal phase of a racemic mesogen, wherein enantiomerically ...
