If I designed a metalens for the ultraviolet region from 270um to 380 um, and I would like to determine the normalized intensity distribution at different wavelengths in this region (for example at 270nm, 298 nm, 334 nm, and 380 nm). note the metalens designed at 290 nm.
so what can I do to do that? can I design the metalens at 290nm and set the plane wave source at each wavelength I would like( start wavelength =stop wavelength =270nm, 298 nm, 334 nm, and 334 nm respectively). or I have to set the plane wave source at (start wavelength=270 and stop wavelength=380nm) but in this situation how I can calculate the normalized intensity and different wavelength in this region (270 nm to 380 nm)
please see attached photo.
please give me an answer if only you make sure.
