My Mobile Apps (Snapshots)

Apps on App Store: MuStripKit, EMpolarization, EMwaveRT

[Some also on Play Store, other apps may have expired (not compatible with recent OS) or only for students in lab/class]

MuStripKit is a versatile microstrip toolkit app for microstrip circuit analysis and design. The app realizes various functions, including microstrip line analysis and synthesis, calculations of input impedance, reflection coefficient, and frequency response in terms of S-parameters. A Smith chart tool is also provided to aid in designing a microstrip circuit. In addition, using a novel multiple 1-D FDTD method, the app shows time-domain simulation of microstrip circuits incorporated with lumped elements, including resistors, capacitors, and inductors in parallel, as well as series connections. Several educational circuit examples are provided to help illustrate the electromagnetic wave propagation in the microstrip circuit. For more information, please refer to "A Microstrip Circuit Tool Kit App with FDTD Analysis Including Lumped Elements," IEEE Microwave Magazine, vol. 16, no. 1, pp. 74-80, 2015, and “M1-D FDTD Methods for Mobile Interactive Teaching and Learning of Wave Propagation in Transmission Lines,” IEEE Antennas and Propagation Magazine, vol. 61, no. 5, pp. 119-126, 2019.

User interface:

- touch on number field to input/change value

- slider may be used to change value

- swipe left/right to select circuit element

- press 'Add'/'Del' to add/delete circuit element in schematic

- tap to select circuit element in schematic

- long press to move circuit element in schematic

EMpolarization is an app to aid teaching and learning of electromagnetics (EM) using mobile devices on the topic of wave polarization. The app is designed to provide interactive visualization to help students better understand wave polarization concepts. Through the use of the app, various polarizations could be explained better with the aid of 2D and 3D animations. Users are allowed to input various wave parameters to see the change in real time in the polarization ellipse and/or handedness. More advanced topics such as polarization ellipse parameters, Poincare sphere and Stokes parameters are also presented. For more graphical interaction with fun, the polarization state is further presented as a point located on Poincare sphere that coincides with the earth globe. For more information, please refer to the article "Teaching and Learning Electromagnetic Polarization using Mobile Devices," IEEE Antennas and Propagation Magazine, vol. 60, no. 4, pp. 112-121, 2018.

EMwaveRT is an app to aid teaching and learning of electromagnetics (EM) using mobile devices on the topic of plane wave reflection (R) and transmission (T). The app is designed to provide effective touch-based interactivity and visualization to help students better understand EM concepts. It is applicable to EM plane wave reflection and transmission for general oblique incidence and polarization. The instructor is able to input or change various parameters and rotate the view angles for interactive teaching. Based on the parameters, the 3D animations of incident, reflected and transmitted waves can be visualized in real time. This allows the students to identify clearly each wave and improves their learning of plane wave reflection and transmission. Through several preset cases of incident angles, the visualizations on mobile devices are illustrated. The app can be used to supplement the 3D TV program available for download from here. For more information, please refer to the article “Teaching and Learning Electromagnetic Plane Wave Reflection and Transmission using 3D TV,” IEEE Antennas and Propagation Magazine, vol. 61, no. 2, pp. 101-108, 2019.
