Earlier visual material, kept for reference. Current results are in the
[Showcase](https://remilab.ai/rfx/showcase/).

Choose a physical question. Each example connects a model to the motion or
response it produces, with its source and evidence scope alongside the picture.
The site plays stored results; it does not run a solver in your browser.

## Start with a field

These teaching examples were generated for this documentation update using the
public Simulation API. They show actual time-domain snapshots on a single mesh;
they are not convergence or RF-accuracy benchmarks.

  
    [![Electric pulse in open absorbing and closed reflecting domains](https://remilab.ai/rfx/gallery/assets/current-visuals/boundary-reflection.png)](https://remilab.ai/rfx/gallery/boundary-reflection/)
    Open space or reflecting walls?
    The same pulsed source with absorbing CPML boundaries and metal PEC walls.

    [![Electric pulse encountering a dielectric interface, compared with vacuum](https://remilab.ai/rfx/gallery/assets/current-visuals/dielectric-interface.png)](https://remilab.ai/rfx/gallery/dielectric-interface/)
    Meet a dielectric interface
    Watch the field respond when the medium changes, with a vacuum comparison.

    [![Electric field forming an interference pattern in a closed metal cavity](https://remilab.ai/rfx/gallery/assets/current-visuals/cavity-standing-wave.png)](https://remilab.ai/rfx/gallery/cavity-standing-wave/)
    Trap a field in a cavity
    See reflections and interference inside a closed conducting domain.

## Explore a design in motion

These archived presentation films show more complex structures and optimization
histories. Their original numbers are historical; the case pages distinguish
phasor replay, real iterations and explanatory interpolation.

  
    [![Dielectric taper profile, reflected spectrum and sensitivities](https://remilab.ai/rfx/gallery/assets/showcase-20260927/taper_traj.jpg)](https://remilab.ai/rfx/gallery/waveguide-taper/)
    2026 paper, original films
    Waveguide dielectric taper

## Read a reference comparison

The earlier [dielectric-slab gallery](https://remilab.ai/rfx/gallery/multilayer_fresnel/) and
[empty rectangular-waveguide gallery](https://remilab.ai/rfx/gallery/waveguide_wr90/) retain their
field, response and derivative artifacts. Both bundles were computed with
rfx 1.6.5 at `1eb551b`. Conductor placement and absorber behavior have changed
since that version, so their recorded results are not current-version benchmarks.
Read each page's precise limits and measurement definitions.

The [patch-antenna diagnostic archive](https://remilab.ai/rfx/gallery/patch_antenna/) is preserved
for traceability. Its stored port setup does not pass current preflight; it is
not a validated antenna showcase.

## More visual experiments to build

These are extensions to develop and validate, not additional films already
published. Their source examples provide a starting point.

choose a [runnable example](https://remilab.ai/rfx/examples/) and keep the model, arrays and plots
together.
