Online documentation can feel like a web of hyperlinks. A structured PDF or linear guide provides a clear step-by-step path from a blank canvas to an analyzed simulation. This comprehensive guide serves as your definitive handbook

Used for periodic arrays, metasurfaces, and thin-film stacks. Ensure the injection plane sits at least half a wavelength away from structures to avoid near-field coupling.

Frequency-Domain Field Monitors: For spatial field profiles. Core Foundations of FDTD Simulation Understanding the Yee

Set the span to completely enclose the cross-section of the waveguide with extra room on the sides.

Use a Mode Source with an angled injection (typically 8 to 12 degrees) to mimic fiber-to-chip coupling.

For structures with thin layers, high-contrast interfaces, or localized fields (like plasmonic hot spots): Add a from the Simulation menu. Position it strictly around the critical interface.
