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?

Yeah, I got Les Moxon's HF Antennas For All Locations, but despite saying it's not much math in the intro it's a lot of dense theory and not very clearly organized. I should get the classic!

    I mean... there are books about the math, which teach you the methods and theoretical basics, and there are books about the practical application that don't really go into the math, but list empirical information about antennas. Both have value.
