A constant index lens for integrated digital electronics

An RF manifold is in general a passive device which effects the distribution of microwave signals in a prescribed fashion. It must accomplish this power distribution with a high efficiency and maintain this level of performance over a prescribed frequency band. In order to achieve high efficiency, it must employ a low loss transmission medium and maintain control of the amplitude and phase of the signals as they pass through the assembly. Other design constraints which significantly affect the electrical performance are volumetric, structural and environmental considerations as well as reproducibility and weight.
