Polychromatic electric field knots [PDF]

open access: yesPhysical 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 (nonparaxial) regime forms nontrivial three-dimensional ...

Pulsed electric field ablation process-the effect of bifurcation stents on electric field and heat distribution [PDF]

open access: yesScientific Reports
Pulsed field ablation (PFA) is a novel non-thermal technique for arrhythmia treatment, capable of targeting the epicardium. However, the effects of coronary bifurcation lesions (BL) and bifurcation stents (BS) on ablation efficacy have not been evaluated.

Electric Field Measurement in Radiative Hyperthermia Applications [PDF]

open access: yesSensors
Oncological hyperthermia (HT) is a medical technique aimed at heating a specific region of the human body containing a tumour. The heat makes the tumour cells more sensitive to the cytotoxic effects of radiotherapy and chemotherapy.

Polariton Electric-Field Sensor [PDF]

open access: yesPhysical 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 ...

Unattended Electric Weeder (UEW): A Novel Approach to Control Floor Weeds in Orchard Nurseries

open access: yesAgronomy, 2023
This study developed an unattended electric weeder (UEW) to control floor weeds in an orchard greenhouse. The UEW was a motor-driven dolly equipped with a spark exposer.

Electrostatic Insect Repulsion, Capture, and Arc-Discharge Techniques for Physical Pest Management in Greenhouses

open access: yesAgronomy, 2022
This article reviews the development of electrostatic apparatuses for controlling insect pests in greenhouses. The apparatuses control insects by repelling them, capturing them, and killing them by producing an arc discharge.

Electrostatic Techniques for Physically Managing Pathogens, Insect Pests, and Weeds in Field and Greenhouse Cropping Systems

open access: yesAgronomy, 2023
The primary focus in pest management across all pest classes, including pathogens, insect pests, and weeds, is on shifting towards methods that do not rely on pesticides [...]

Recent Sensing Technologies of Imperceptible Water in Atmosphere

open access: yesChemosensors, 2022
Accurate detection and quantitative evaluation of environmental water in vapor and liquids state expressed as humidity and precipitation play key roles in industrial and scientific applications. However, the development of supporting tools and techniques

Use of a Pair of Pulse-Charged Grounded Metal Nets as an Electrostatic Soil Cover for Eradicating Weed Seedlings

open access: yesAgronomy, 2023
An electrostatic technique was developed to generate a simple physical method to eradicate weeds in crop fields. The proposed apparatus consisted of double-expanded metal nets connected to a pulse-charging type negative voltage generator and a grounded ...
