ANTENNA FDTD STUDIO · APPLICATION EXAMPLE

Intelligent Reflecting Surfaces

A horn-fed reflecting array, from element-phase synthesis to its modeled geometry and exported plots. Explore the supplied Intelligent reflecting arrays example in Antenna FDTD Studio.

01 · SYNTHESIS & MODEL

From phase map to array geometry.

**Reflectarray synthesis workspace**The supplied synthesis workspace shows a hexagonal 64-element target-phase map, with 10 GHz frequency and 18 mm spacing along both lattice axes.

**Horn-fed array model**The supplied modeling workspace shows the horn feed above the reflecting array, with domain bounds, dimensions and element geometry history intact.

02 · RECORDED FIELDS

Follow the field across the array.

Recorded electromagnetic-field animation · all 24 exported frames, in their original order and at the original 12 fps playback rate.

03 · RADIATION PATTERNS

Explore the radiated response.

**3D radiation pattern**The supplied 3D radiation export, labeled Intelligent reflecting arrays, retains the array geometry and original −6 to 15 dB color scale.

**Radiation cuts**Pattern versus theta, alongside the φ = 0° / 180° and φ = 90° / 270° polar cuts. The original plots retain their respective −12 to 15 dBi and −10 to 15 dBi radial scales.

04 · FREQUENCY RESPONSE

Magnitude across frequency.

**Magnitude · 8–12 GHz**The supplied plot shows magnitude in dB versus frequency from 8 to 12 GHz. The export does not identify the specific S-parameter.

Images retain the supplied pixels, axes and color scales. The workspace screenshots show a simulation in progress; the plots are separate supplied exports. The video is a web-playback copy of the supplied animation, preserving its frame count, dimensions and timing. This page presents the recorded material and does not run a solver.
