Ansys Lumerical RCWAは、回折格子などの周期的配列を伴う多層構造の迅速な光学解析に最適です。 


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.

Ansys Lumerical’s Component Level Tools

This webinar will start with an overview of the broad set of component level solvers it offers with an emphasis on FDTD and MODE. It will then show how these solvers can be used to simulate and optimize novel designs in a wide range of applications including micro-LEDs, augmented reality, magneto-optics and lasers.

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.

Photonic Crystal Slab (RCWA)

This example demonstrates the essential functions of the RCWA solver. The reflection and transmission from a silicon photonic crystal slab are calculated, and the electric field inside the slab. The results with the different number of k-vectors will be compared to simulation results from the literature through convergence testing. Lastly, the reflection and transmission are calculated as frequency, incident angle, and polarization.

Metalens – Zemax Interoperability

This example aims to design diffractive metalens consisting of cylindrical nanorods. The nanorods' radius and arrangement are tailored to create a desired phase profile on the metalens surface. The design is verified in Ansys FDTD, RCWA (Rigorous Coupled-Wave Analysis), and OpticStudio through near- and far-field analyses.
