SOLVE THE UNSOLVABLE
Rapid Analysis of Periodic Structures With Lumerical RCWA
Design multilayer structures with periodic variations quickly with Lumerical RCWA. Using a semi-analytical technique, RCWA is much faster than direct simulations of Maxwell’s equations. Designers can accurately capture interference effects and evaluate the transmitted and reflected optical fields under plane wave illumination.

Versatility Through Rapid Analysis of Periodic Multilayer Structures
Develop multilayer structures with periodicity and surface patterning with Lumerical RCWA. RCWA captures interference effects and evaluates the electric and magnetic fields inside the multilayer structure for plane wave illumination. Quickly obtain the optical response of a structure with the fraction of incident power transmitted and reflected and the power and phase of each grating order. The capabilities of RCWA make it an ideal solution for rapid prototyping of periodic structures such as diffraction gratings, metalenses, and photonic crystals.
Key Features
From capturing the electric and magnetic field distributions, to transmission and reflection and evaluation of power in each grating order, RCWA provides fast simulations of complex multilayer stacks with surface patterning.
- RCWA Solver
- Interoperability via Scripting
Based on the Rigorous Coupled Wave Analysis method, Lumerical RCWA complements Lumerical FDTD and STACK by providing a rapid simulation of light scattering for periodic and multilayer structures.
Lumerical RCWA tools are interoperable through the Lumerical scripting language, Python and Matlab APIs.
