Thanks!

Well that’s disappointing, i really tried optimizing it and it worked well on the few devices I tested (I have an iPhone 13 Pro that handles it well). I will see what I can do to make it more smooth.

And yes I am working on adding different kind of pec obstacles, dialectic materials and ohmic conductive materials.

The challenge is to keep the solver cheap while preserving reasonable accuracy.

May I ask what phone do you have ?

Thanks for the feedback:)

    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)
