A microwave transmission line courseware based on multiple 1-D FDTD method on mobile devices

This paper presents a multiple 1-D finite-difference time-domain (FDTD) method to analyze transmission line with stubs on mobile devices for educational courseware. The update equations of the proposed method are given for the main transmission line and open/short-circuited stubs. The proposed method is efficient and requires low memory compared with 2-D or 3-D FDTD method. It realizes an efficient real-time simulation of microwave transmission line circuit on mobile devices without lagging. The proposed multiple 1-D FDTD method is programmed and demonstrated on the mobile device as a courseware.
