Periodic surfaces use identical repeating elements across the entire structure. Quasi-periodic surfaces vary the element properties across the surface to achieve specific performance goals.

Both enable advanced electromagnetic control, and TICRA is the only commercial tool that designs and analyses both seamlessly.

TICRA tools support single and multi-layer structures, shaped surfaces, offset geometries, and both planar and curved configurations. The extensive geometry library includes canonical elements, tabulated data and surface distortions for accurate real-world representation.

Periodic and quasi-periodic surfaces manipulate electromagnetic waves through repeating element patterns, enabling high-performance solutions in compact, potentially deployable packages.

They excel where traditional designs cannot match the beam efficiency, multi-band operation or low radar signature requirements.

Yes. TICRA tools model surface distortions, element misalignments and manufacturing tolerances directly in electromagnetic analysis. You can assess performance impact and optimise designs to maintain requirements despite real-world imperfections.

TICRA employs Periodic Method of Moments solvers for accurate unit cell analysis and a hybrid PMoM–Physical Optics approach for electrically-large surfaces.

Each method is applied appropriately based on problem size and geometry.

TICRA tools are validated across numerous space, defence and science programmes. Correlation studies show excellent agreement between predictions and measured radiation patterns and performance metrics.

Large-scale direct optimisation of quasi-periodic surfaces with hundreds of thousands of elements typically completes in seconds, enabling rapid design iteration and exploration compared to general-purpose solvers.
