Commercialized, low C-SWAP (Cost, Size, Weight and Power), software defined communications apertures will substantially increase network capacity in future 5G wireless networks. We advocate using high gain, electronically steerable antennas for small cell radio access networks, backhaul and millimeter wave applications. The steerable beam functionality can provide elevated data rates, reduced power...
We present experimental results showing the application of transistor-embedded metamaterials to realize nonlinear and acousto-optic metamaterials. Due to their nonlinear properties, transistors can be used to realize a large variety of useful radio frequency (RF) functions and applications. These include switches, oscillators, amplifiers, tunable resistors and capacitors, and other devices. Metamaterials...
Functional metamaterials provide useful properties for the design of electromagnetic devices. In this work we demonstrate that functions including high nonlinearity and amplification can be included in metamaterials to realize time reversal imaging.
We present the design and experimental implementation of an RF limiter metamaterial using a sheet of nonlinear metamaterials. We demonstrate that complementary electric inductive-capacitive resonators loaded with nonlinear p-i-n diodes can act as RF limiter unit cells. We design and fabricate limiter metamaterials and compare them to traditional circuit limiters. Our limiter metamaterial exhibits...
