PROJECT TITLE :

Design and Full Characterization of Planar Active Magnetic RF Metamaterials

ABSTRACT:

Applications of metamaterials are limited by parasitic resistive losses. We have a tendency to present the design and measurement of split ring resonators with embedded active field impact transistor circuits comprising a magnetic metamaterial. We show that the imaginary part of the effective permeability changes sign inside the bandwidth of the negative differential resistance region, creating a stable gain medium. We present experimental reflection and transmission measurements showing a sign modification within the permeability loss term and 2 applications of such a metamaterial. use as a mu-negative close to field parasitic part for small magnetic antennas and as an amplifying material in free house. We tend to show the active metamaterial can give property enhancement compared with connected passive structures in each applications, providing a path to overcoming parasitic loss in previously demonstrated metamaterial structures.
