Abstract:

Our work concentrated on on-wafer delay lines based on liquid crystals. These non-dispersive devices were tested in the range of 1- 110 GHz and exhibit phase change on the order of 300 deg.cm. We have designed also series of other tunable devices based on liquid crystals such as band pass and notch filters and patch antennas operating at 60 and 85 GHZ. The nonlinear effects of two wave mixing were studying in magnetic structures. It allowed us to amplify the week signal by 25 dB as well as to create the comb of frequencies equally spaced. We also developed a deposition process Metallo-organic decomposition-MOD of hexagonal ferrites on metallic templates Pt. Finally, we demonstrated the feasibility of using hexagonal ferrite thin films to develop planar millimeter wave phase shifters and notch filters.
