I just downloaded the 32 bit version of FTDT to learn how the program works, so not an experienced FDTD user. I am using FDTD to analyze a small lens immersed in another material. I am using the substrate with appropriate refractive index to model the immersive material. IS the wavelength I specify in the simulation the wavelength in air, or the wavelength in the substrate material?

      Hi,

      The wavelength defined in the input plane / point source parameters is always the free space wavelength (ie. in air).
