Light-activated modulation and coupling in integrated polymer-liquid crystal systems [PDF]

, 2014
We explore the transfer of an incident light pattern onto the liquid crystal (LC) bulk in a photorefractive cell through an integrated photoconducting layer that modulates the electric field applied to the device.

Effect of internal fractures on mechanical properties and failure of sandstone under multi-physical fields

Heliyon
Under deep mining conditions, rocks are subjected to complex multi-physical fields and can contain numerous pores and fractures. To explore the influence and correlation of these factors on the physical and mechanical properties of fractured rock samples,

The Fractal Characteristics of Rough‐Fractured Rock Masses Based on THM Multi‐Field Coupling

Engineering Reports
Degradation of the self‐similarity of fracture systems in high‐temperature and high‐stress environments can lead to inaccurate predictions of underground rock mass structures, restricting the reliability of geothermal reservoir development and deep rock ...

Performance optimization for magnetoelectric antennas based on a multi-field coupling analysis model

Journal of Applied Physics
This paper presents a multi-field coupling model for magnetoelectric (ME) antennas, encompassing a ME film, electrode layers, and a substrate featuring a cavity structure. This model accounts for the nonlinear magnetoelastic coupling within the radiation layer and employs a combined DC and AC simulation methodology to capture the antenna's radiation ...

Application of Advanced Multi-Parameter Monitoring in Concrete Structure Defect Detection: Integrating Thermal Integrity Profiling and Strain Analysis

Buildings
Thermal Integrity Profiling (TIP) effectively monitors concrete integrity. TIP detects structural defects and locates them through anomalies in hydration–temperature curves. However, TIP alone cannot accurately identify the defect types.

The Multi-Field-Coupled Model and Optimization of Absorbing Material's Position and Size of Electronic Equipments

Journal of Mechatronics and Applications, 2010
There are three fields in electronic equipment such as structure deformation (S), temperature (T), and electromagnetic (EM) fields. Both deformation and temperature will affect the electromagnetic shielding performance of the equipment considerably, particularly in the case of enclosure with small volume and high packaging density. Because the position
