Reconstruction of the Near-Field Electric Field by SNOM Measurement [PDF]

open access: yesNano Letters, 2023
Scanning near-field optical microscope (SNOM) with nanoscale spatial resolution has been a powerful tool in studying the plasmonic properties of nano materials/structures. However, the quantification of the SNOM measurement remains a major challenge in the field due to the lack of reliable methodologies.

Electric field effects in RUS measurements

Ultrasonics, 2010
Much of the power of the Resonant Ultrasound Spectroscopy (RUS) technique is the ability to make mechanical resonance measurements while the environment of the sample is changed. Temperature and magnetic field are important examples. Due to the common use of piezoelectric transducers near the sample, applied electric fields introduce complications, but

Phase measurement for electric field tomography

Physiological Measurement, 2008
The basic principles of electric field tomography (EFT) are briefly explained. EFT system numerical simulation results are given. The comparison of images reconstructed by systems with planar and round electrode arrays is presented. Some aspects of transmitting and measuring stages are discussed.

The Measure of Atmospheric Electric Field

2011
We have developed a prototype of a sensor able to detect and measure electric fields in the atmosphere. The atmosphere is a gaseous envelope gravitationally bound to the Planet. Different atmospheres have very different properties. For instance, the atmosphere of Venus is very thick and cloudy, and is responsible for producing the very high surface ...

Arrays for Tensor Measurements of the Electric Field

Symposium on the Application of Geophysics to Engineering and Environmental Problems 2003, 2003
The study of resistivity anisotropy in heterogeneous media is a complex problem that needs developing the special field technology and interpretation technique. Traditional anisotropic resistivity survey requires performing a set of azimuthal measurements.

Electric field measurement by a LiNbO 3 probe

SPIE Proceedings, 2007
Optical devices have the potential for large scale integration and can be successfully used in mission critical environments; in particular optical probes interacting with electric fields can be used in several electromagnetic compatibility (EMC) and industrial, scientifical and medical (ISM) applications. We describe an electro-optical device based on

Electric-Field Shielding and Measurement

1967 IEEE Electromagnetic Compatibility Symposium Record, 1967
Using quasi-static relationships, a fairly simple derivation for the electric-to-electric-field shielding effectiveness was demonstrated. Shielding-effectiveness computations based on this simple approach appear identical to those based on a more rigorous formulation using scattering theory and numerical integration.
