摘要
第3届欧洲物理奥林匹克竞赛的实验试题为无线电波的传输,试题利用1组无线电波发射器与接收器,探讨了等厚干涉、介质对波的吸收、波导中波的衰减、介质的折射率和倏逝波等物理现象.本文介绍了该实验试题内容和详细的解答.实验试题设计新颖,可开设为电磁波的综合性实验.
The experimental question of the 3rd European Physics Olympiad experimental exam was the propagation of radio waves.Using a pair of radio waves emitter and receiver,some meaningful phenomenon related to interference of equal thickness,the attenuation of wave in medium,the decaying modes in a waveguide,the refractive index of medium and evanescent wave was studied.This paper introduced the experimental question content and detailed solution.The experimental question was designed and could be used as a comprehensive experiment of electromagnetic wave.
