Realization of optical diffusers with disordered dielectric Huygens metasurfaces

Since conventional diffusors lack the potential for on-chip integration, a random arrangement of carefully designed nanoparticles on a surface is considered to realize an optical diffusor. The response of the random surface is computed with the a T-matrix method. The T-matrix of the individual scatterers up to octupolar order is computed with JCMsuite.
