An Interactive Web-based Learning Module for Metallic Rectangular Waveguides

To improve the interactive animated teaching platform developed in the electromagnetics revitalization program in Taiwan, a project was granted by IEEE MTT-S Education Committee under the SIGMA-WE initiative in the end of 2018. New interactive web-based learning modules have also been voluntarily developed. Among them, a learning module for metallic rectangular waveguide will be introduced in this paper. This module shows the animation of mode patterns of a rectangular waveguide, such as the electric field of TE
₁₀
mode and the magnetic field of TM
₁₁
mode. Cut planes to show the field patterns are freely selectable by users. Operating frequency is also a user-input parameters to facilitate the learning of cutoff behavior. The web-based learning module is developed using JavaScript and related cross-browser libraries.
