By using the previously unwanted dispersive properties of metal mesh artificial dielectrics, we propose a novel design for a flat prism.

Abstract
By using the previously unwanted dispersive properties of metal mesh artificial dielectrics, we propose a novel design for a flat prism. This is a device that steers an incident plane wave by a given angle based on its frequency. This is achieved by using existing graded index theory and further understanding of the dispersion effects in metal mesh grids. Such a device would act as an alternative to diffraction gratings and operate over the frequency range of 100-200 GHz.| File | Dimensione | Formato | |
