a website to help students visualize the electromagnetic field

I’ve been building this simulator as a side project aimed to help students understand and visualize electromagnetic phenomena such as radiation, near field effects, polarization, wave interference and diffraction.

You can:

  • 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 :)

What do you think I should add?

Thanks!

I really should add folded dipole, moxon and slim Jim antennas. That shouldn’t be too complicated (under thin pec wire approx)

Adding ground plane at different heights is also a great idea that would not be difficult to add.

About adding different materials, I am not sure what’s the best way to let the user set their geometry without turning this into a full 3D engine. (I might in the future)
