Pyroelectric Plate with Magnetoelectric Effect

Journal of Applied Mathematics and Physics 2024年第5期12卷 1616-1625页

作者： pavel Grinfeld Michael Grinfeld Mathematics Department Drexel University Philadelphia USA The U.s. Army Research Laboratory WMRD Aberdeen Proving Ground USA

In dynamic problems the electric and magnetic fields are inseparable. At the same time, a multitude of electrostatic and magnetostatic effects permit mutually independent description. This separation appears to be possible and thermodynamically consistent when the bulk energy density depends only on the polarization density or, alternatively, on the magnetization density. However, when the bulk energy density depends simultaneously on the both densities, then, the electrostatic and magnetostatic effects should be studied together. There appear interesting cross-effects;among those are the change of the internal electrostatic field inside a specimen under the influence of the external magnetic fields, and vice versa. Below, in the framework of thermodynamic approach the boundary value problem for magnetoelectric plate is formulated and analyzed. The exact solution is established for the isotropic pyroelectric plate.

A novel dual-core fiber-optic gyroscope with independent rotation rate measurements in different cores of a dual-core optical fiber

引用

Optoelectronics Letters 2024年

作者： EMIL A.MILIKOV VIACHEsLAV V.ZEMLYAKOV pavel s.ANIsIMOV GAO Jiexing 2012 Labs Central Research Institute Huawei Technologies Co. Ltd.

We introduce an all-fiber stationary phase shifter for a fiber-optic gyroscope which simultaneously provides phase shifts of opposite signs in different cores of the dual-core optical fiber. We propose a new dual-core fiber-optic gyroscope in which different cores of the dual-core optical fiber provide independent rotation rate measurements. The device enables implementation of a differential scheme， which ensures the stability of the measured phase shift. As a computer simulations result， the accuracy of the rotation rate sensing increased by up to 10 times at typical noise levels.
