Metasurface Studio / Metasurface Designer

Three-bedroom home

One bathroom. A router in the living area. A surface that redirects the signal.

The house

Adapted from your reference floor plan into 3 bedrooms / 1 bathroom. Open kitchen, dining and living areas connect through the central hall.

Floor area: 128.8 m²
Signal frequency: 60 GHz
Walls / openings: Full-height walls, real door gaps

Layout and scale assumptions

The image is a layout reference, not a measured building survey. Bedrooms replace the stair area. The bathroom entrance faces the hall; its opening is included in the propagation geometry. Wall height is independent of the cutaway view.

Placement

Coordinates are x, y, z in metres. Select a device to inspect it in 3D.

The bathroom wall blocks the direct router-to-UE path.

Drag the coloured axes to move the panel. It stays vertical; facing 0° points east, 90° north. Run a new comparison after changing placement or frequency.

Half-wavelength spacing changes the physical panel size with frequency.

Calculated cell phases

0 → 2π · phase colour scale

φ = k[(d_TX,cell + d_cell,UE) − (d_TX,centre + d_centre,UE)]. Each cell compensates its path length to focus on the UE. The solve also calculates a global phase offset against the baseline channel.

Unit-cell geometry and response are validated separately with HFSS or WiTwin Maxwell. Repeating the cell forms the metasurface used in this coverage scene.

Current array: ideal phase model. A validated unit-cell response has not been linked to this panel yet. Coverage results do not validate a manufactured unit cell.

Coverage solver

Checking coverage solvers…

Compare the same scene with and without the surface. A completed, verified result replaces the geometry preview.

What this validation covers

The selected coverage solver evaluates the declared scene and array. Paths and powers are tied to that solver and submitted configuration. Room measurements, material calibration and unit-cell response validation remain separate.

Sionna traces a native ideal RIS. WiTwin Channel / RayD traces the baseline and line-of-sight legs, then combines them with an ideal analytical aperture. This is explicitly a hybrid surface model, not native programmable-RIS support.
