RCWA Simulation Control Panel #

This section introduces the simulation control panel for the Rigorous Coupled‑Wave Analysis (RCWA) solver.

The RCWA solver is a semi‑analytical simulation tool based on rigorous coupled‑wave analysis. It is used to efficiently and accurately analyze the optical response of multi‑layer structures with periodic variations along the propagation direction (such as diffraction gratings, metasurfaces, and photonic crystals) under plane‑wave incidence, including reflectance, transmittance, diffraction efficiency, and internal field distributions.

The functions of each button on the control panel are shown in the figure below:

	Name	Description
Design	To Design	Switch back to the Design view to access tools for structure creation and solver settings, etc.
Graphics	Translucent	Set the transparency of the structure; 1 means opaque, 0 means fully transparent.
	Hide Material	Hide the material structure in the view; enabled when checked.
	Hide Fields	Hide the field distribution in the view; enabled when checked.
Progress	Status	Display the current simulation status and progress.
	Tool	Control the opening and clearing of simulation data files.

The structural components of the RCWA solver are common to other solvers. Users can also add auxiliary components: custom mesh.

Mesh #

Used to apply finer mesh refinement to specific regions.
