Reflectarray Design Using a Discrete Dipole Framework

IEEE Open Journal of Antennas and Propagation, 2023
We propose and numerically validate a patch reflectarray modeling approach suitable for small patches that describes each patch as a pair of polarizable magnetic dipoles.

Effect of Bandage Materials on Epidermal Antenna

Engineering Proceedings, 2023
This study explores the effect of different types of bandages on the performance of an epidermal antenna. Three identical dipole antennas are designed on three different types of bandages, and the measured reflection coefficients, S11, show that the ...

Inversion of a Thunderstorm Cloud Charging Model Based on a 3D Atmospheric Electric Field

Applied Sciences, 2018
The measurement of the atmospheric electric field is of great significance for the study of thunderstorm cloud charge models. Traditional electric field meters can only measure the vertical component of the atmospheric electric field, and thus it is ...

Scattering of color dipoles: from low to high energies [PDF]

, 2002
A dipole-dipole scattering amplitude is calculated exactly in the first two orders of perturbation theory. This amplitude is an analytic function of the relative energy and the dipoles' sizes.

How Do Surface Polar Molecules Contribute to High Open‐Circuit Voltage in Perovskite Solar Cells?

Advanced Science, 2023
To date, the improvement of open‐circuit voltage (VOC) offers a breakthrough for the performance of perovskite solar cells (PSCs) toward their theoretical limit. Surface modification through organic ammonium halide salts (e.g., phenethylammonium ions PEA+

The Improvement and Application of the Geoelectrochemical Exploration Method

Applied Sciences, 2023
The anionic and cationic species of elements from deeply buried deposits migrate to the near surface driven by various geological forces. The geoelectrochemical exploration method (GEM), derived from CHIM, consists of the application of an electric field

On the Energy Dependence of the Dipole-Proton Cross Section in Deep Inelastic Scattering [PDF]

, 2010
We study the dipole picture of high-energy virtual-photon-proton scattering. It is shown that different choices for the energy variable in the dipole cross section used in the literature are not related to each other by simple arguments equating the ...

Spontaneous Polarization Calculations in Wurtzite II-Oxides, III-Nitrides, and SiC Polytypes through Net Dipole Moments and the Effects of Nanoscale Layering

Nanomaterials, 2021
Herein, the spontaneous polarization in crystals with hexagonal symmetry are calculated as a function of the number of monolayers composing a nanostructure by adding the dipole moments for consecutive units of the nanostructure.

The X-ray Cluster Dipole [PDF]

, 1997
We estimate the dipole of the whole sky X-ray flux-limited sample of Abell/ACO clusters (XBACs) and compare it to the optical Abell/ACO cluster dipole.
