Modeling and validation notes
Conformal height profiles use stepped planar tiles. Unit-cell phase calibration and full-array behavior require separate validation.

About these recorded fields
These are recorded outputs from the original Antenna FDTD Studio 3D solver, shown as clear signed-component sections through the recorded 3D fields with the actual CAD geometry. Dipole and horn air domains are expanded; the array outline is a projected CAD footprint over near-surface field sections. Each example has 192 recorded time samples. Domain guides are hidden and field edges fade visually; no fields are invented outside the recorded domain. Scalar fields are interpolated and colorized during playback, with contour lines and a separate high-resolution CAD layer. The array uses simultaneous excitation and reports active reflection, not a full S-matrix.
