From Homogenization to Validity Limit of Geometrical Optics Author: Taoufik Ghabara, Faouzi Ghmari and M. Salah Sifaoui Abstract: Geometric prescription pills for weight loss optics approximation for emissivity from triangular surfaces was compared with exact scattering predictions from electromagnetic theory. Rigorous electromagnetic scattering theory was numerically formulated based on the differential method. We have used [...]
