Hi,
I would be happy to help you, but I would more specific information about the samples you have to see if we can match the measured values. Do you have sample images or drawings showing the distance between spheres, number of layers etc? Could you also send me the actual measured curves? Finally at which wavelength range where these measurements taken?
