Design and realization of transistor-embedded active RF metamaterials

Summary form only given. We present several results that use transistors within the context of metamaterials. Transistors are a fundamental device in the construction of several RF systems and applications. The basic device physics of the transistor allow for the convenient construction of variable resistors, oscillators, switches, and amplifiers. Embedding transistors within the confines of a split ring resonator (SRR), metamaterials can be designed to have a tunable resonant frequency, a tunable bandwidth, controlled loss cancellation and gain, and controlled oscillation. We will demonstrate how to design and realize all of the aforementioned properties.
