AI赋能下“电磁场、微波技术与天线”可视化教学改革探索

Exploration and Visual Teaching Reform of AI-Electromagnetic Fields, Microwave Technology, and Antennas Course

摘要: “电磁场、微波技术与天线”是电子信息类专业一门非常重要的核心课程，概念抽象，电磁场电磁波看不见又摸不着，理解非常困难。传统“灌输式”的教学模式并不适合于该课程。针对上述教学痛点，AI提供了新的解决思路，其可以将抽象概念可视化，帮助学生理解。对此，本文基于成果导向教育(OBE)理念，采用AI辅助教学，对概念抽象性强的电磁场、微波技术与天线课程开展可视化教学改革。深入分析研究学情、教情，基于Matlab仿真和AI辅助教学将三维模拟仿真引入到课堂教学。以平面波极化和对称振子天线为例，实现电磁波三种极化以及对称振子天线三维、二维方向图的可视化仿真，理论讲解与仿真实践相结合，建立符合成果导向教育的教学策略。

Abstract: “Electromagnetic Fields, Microwave Technology, and Antennas” is a very important core course in the field of electronic information. It has abstract concepts, Electromagnetic fields and electromagnetic waves are invisible and intangible, making students extremely difficult to understand. The traditional “lecture-style” teaching model doesn’t really fit for this course. To address this teaching pain point, AI offers new ways to solve problems; it can visualize abstract concepts and help students understand them. In response, this article is based on Outcome-Based Education (OBE) concepts and uses AI-assisted teaching to carry out visual teaching reforms for highly theoretical courses like Electromagnetic Fields, Microwave Technology, and Antennas. It deeply analyzes students’ learning situations and teaching conditions, introducing 3D simulation into classroom teaching based on Matlab simulations and AI-assisted instruction. Taking plane wave polarization and symmetrical dipole as an example, it achieves visual simulations of three types of electromagnetic wave polarization and the 3D, 2D radiation patterns of the symmetric dipole antenna, integrating theoretical explanations with simulation practice, and establishes a teaching strategy in line with Outcome-Based Education.
