I have been building this simulator as a side project aimed to help students understand and visualize electromagnetic concepts such as radiation, near field effects, polarization, coupling, wave interference and diffraction. The simulator is interactive and runs on the browser.

The simulator lets the user:

place multiple, diffrent radiation sources and set their parameters (geometery, amplitude, phase and more)
place perefect wire conductors, PEC plane and poke slots in the plane to create diffraction patterns
observe the electric field, magnetic field, energy flow field, energy density or radiation pattern
zoom in and out and translate the canvas
change the simulation resolution, frequency and propogation speed and some other parameters

I hope someone might find it useful and I’d love to hear what people think :)
Intended for computers but also works on most mobiles (with a diffrent UI).
