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 TE10 mode and the magnetic field of TM11 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.
