Parasitic scattering
WebFeb 11, 2008 · We develop an approach to utilize anisotropic metamaterials to solve one of the fundamental problems of modern plasmonics---parasitic scattering of surface waves into free-space modes, opening the road to truly two-dimensional plasmonic optics. We illustrate the developed formalism on the examples of plasmonic refractor and plasmonic … WebA new 4-port S-parameter de-embedding methodology is presented. This de-embedding technique considers distributed on-wafer parasitics in the millimeter wave band (f > 30 GHz). The procedure is based on simple analytical calculations and requires no equivalent circuit modeling or electromagnetic simulations. Using both EM theory and HP-ADS …
