摘要: Abstract The scattering performances of realisable quadratic residue diffusers (QRDs) have been tested. has compared to (i) the original design theory QRD; (ii) optimum diffusion; and (iii) performance plane curved reflectors. QRDs do produce similar diffusion that predicted by theory. Only at low frequencies, however, is this close diffusion. For oblique incidence QRD produced greater than panels. At normal incidence, panel was as good QRD.
