01 / THE QUESTION

Editorial guide

Can the studio evolve electric and magnetic fields on a staggered grid to show single- and double-slit diffraction in 2D and 3D?

02 / WHAT THE RECORD SAYS

Source passage

At 1100 2D time steps, summed detector signals in relative units were zero for a closed screen, 0.0465 for one slit, and 0.1405 for two slits

03 / LIMITS & OPEN POINTS

Source passage

These checks establish a functioning discrete Maxwell demonstration. They do not establish convergence to a continuous solution or experimental agreement.

04 / THE NEXT QUESTION

Editorial guide

Convergence to a continuous solution and agreement with experiment remain untested; the outer boundary is a lossy sponge rather than a perfectly matched layer.

05 / CHECKS IN THE RECORD

Source passage

- python -m unittest discover -s tests -v: 27 checks, including the 3D Courant limit, source-free magnetic divergence, periodic plane-wave temporal recurrence, field past a 3D aperture, and standalone PNG equality. - node tools/check_maxwell.cjs: opaque screen has zero downstream detector energy; a single slit transmits; double-slit total detector intensity exceeds single-slit; the central interference lobe exceeds an adjacent trough; both polarizations are finite and transmit. - node tools/check_optics.cjs: existing ray optics checks still pass. - node --check web/maxwell.js, plus full standalone script syntax check.
