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?

Oo, cool!
I don’t know enough to edit and make more antennas. But suggestions for more defaults / things I have questions about:

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)
