**课程名称：** COMSOL Multiphysics® **铁电材料仿真** **课程概述：** 本课程是一门精炼的COMSOL Multiphysics®铁电材料仿真入门课程，旨在提供直观且有针对性的教学。讲师拥有丰富的教学经验，已在全球105个国家教授超过5000名学生，并拥有17篇国际学术论文发表（包括Nature Materials和Result in Physics等期刊），研究领域涵盖有限元仿真、DFT仿真以及Matlab、Python和Simulink分析。讲师也是Udemy上畅销的COMSOL课程作者，并会根据学生反馈持续更新课程内容。 **学习目标：** * 掌握铁电材料模型的创建。 * 学会仿真铁电材料的迟滞曲线。 * 通过Jiles-Atherton模型模拟迟滞现象。 * 学习使用域间耦合（Interdomain coupling）、钉扎损耗（Pinning Loss）等高级功能。 **什么是铁电性？** 铁电性是一种非导电晶体（电介质）所表现出的特性，其特点是具有自发极化（正负电荷中心分离，导致晶体一侧带正电，另一侧带负电）。这种极化方向可以通过施加适当的电场来反转。铁电性名称来源于与铁磁性（如铁材料中发生的现象）的类比：铁原子本身是微小的磁体，会自发地排列成称为铁磁畴的团簇，而这些畴的方向可以通过外部磁场进行定向。 **课程声明：** 本课程未获得COMSOL AB的任何官方关联、认可或赞助。COMSOL Multiphysics®是COMSOL AB的注册商标。所有提及COMSOL Multiphysics®软件仅用于教育目的。如需官方COMSOL支持、培训和授权，请参阅官方软件提供商。
Welcome to the COMSOL Multiphysics® course on Ferroelectric material simulation. This is a quick course. Lectures are designed to the point. About the InstructorI have instructed more than 5000 students till the year 2021, across 105 countries.Till 2021 I have 17 international publications (including publications at nature materials, Result in Physics, and Optical fiber technology) almost all containing some of the other modeling and simulation involving finite element simulation or DFT simulation or analysis using Matlab Python or Simulink.I am the author of the best-selling COMSOL courses on Udemy.COURSE is Updated constantly with the help of feedback from the students.What you will learn in this course:Ferroelectric Material SimulationLearn to create a Ferroelectric modelLearn to simulate the hysteresis curveModel Hysteresis using Jiles-Atherton model.Learn to use Interdomain coupling, Pinning Loss, etc.Ferroelectricity is a property of certain nonconducting crystals, or dielectrics, that exhibit spontaneous electric polarization (separation of the center of positive and negative electric charge, making one side of the crystal positive and the opposite side negative) that can be reversed in direction by the application of an appropriate electric field. Ferroelectricity is named by analogy with ferromagnetism, which occurs in such materials as iron. Iron atoms, being tiny magnets, spontaneously align themselves in clusters called ferromagnetic domains, which in turn can be oriented predominantly in a given direction by the application of an external magnetic field.See you in the courseDisclaimerThis course is not affiliated with, endorsed by, or sponsored by COMSOL AB.
