Ghent, Belgium – March 18, 2026 – PlanOpSim NV (“PlanOpSim”), a leader in advanced metaoptics simulation, is proud to unveil its latest innovation – the Split Area ASM (Angular Spectrum Method), a game-changing feature that dramatically expands the boundaries of metaoptics analysis.
Designing large area metasurfaces has long posed a challenge to the industry. Traditional full wave simulation methods such as FDTD have been limited to just a few micrometers, while approximation techniques like LPA (local periodic approximation) can stretch this range to mere millimeters or a few million scatterers. For engineers and researchers, memory bottlenecks during analysis have been a persistent hurdle when working with extensive metaoptics designs.
With the January 2026 release, PlanOpSim’s Split Area ASM shatters these limitations, enabling the analysis of record-breaking large metasurfaces with up to 900 million scatterers—equivalent to a 15mm x 15mm structure with a 500nm unit cell. This unprecedented capability empowers users to simulate and design far larger components than previously possible, marking a major step forward in metaoptics technology.
“Our Split Area ASM feature allows for far-field analysis of components that were once considered too large to handle,” said Lieven Penninck, CEO of PlanOpSim. “This achievement demonstrates our commitment to delivering THE tool for metasurface design and analysis, opening new possibilities for academic and industrial innovation.”
PlanOpSim invites users and partners to experience this new capability and explore the future of metaoptics design with the Split Area ASM feature. For more information, visit www.planopsim.com.
