The proposed research will investigate, develop and test an optimized FNF technology and its associated devices with integrated matching networks, optimally matched to radar system feed networks over the entire operational frequency band.. This research is will be the basis for the development of a simplified and facilitated installation of FNF devices in the existing radar systems due to adequate matching which will eliminate the need for an additional circuitry to compensate for undesirable high losses and high reflections. The research is expected to establish a detailed understanding of the effects of fractal structure waveform selectivity on two- port theory and quantification of techniques for FNF design and characterization. The FNF devices are completely passive and self-contained. They require neither external power source nor additional digital signal processing at the output to achieve enhanced SNR up to 12 dB. In addition, the characterization of the FNF devices will include advanced and uniquely configured measurements of: insertion loss, VSWR, and phase-amplitude ripple. Results: Design and fabricate optimized and matched FNF devices, including the appropriate microwave matching network. This Phase II will also include the integration of the matching network hardware into the X-band FNF device and result in device that has the potential to be inserted into operational radars for preliminary tests.
