mmWave Channel Modeling with Diffuse Scattering in an Office Environment

To accurately predict channel characteristics for millimeter wave frequencies, propagation modeling must account for diffuse scattering effects. This example uses Wireless InSite’s diffuse scattering capability to perform simulations of an indoor wireless network.

Fish-Eye Beam-Splitter
Realizing All-Dielectric Devices from Transformation Electromagnetics
A team from Oxford and the University of London fabricated and tested a 2-D generalized Maxwell fish-eye lens has been from all-dielectric polymer/ceramic composite materials. The graded refractive index profile of the lens, discretized into a concentric-ring structure, functioned as a two-way beam splitter. Epoxy composites, with a broad dielectric constant range that can be precisely controlled, were used to cast the lens using a low-cost manufacturing method that can readily accommodate different geometries.
