An optimal strategy for cascading phased-array deflectors is presented that allows for high-resolution random-access beam steering with continuous scan-angle control but requires a minimum number of control lines. The system is analyzed theoretically by use of a Fourier optics approach and then verified experimentally. A pair of 32-channel optical phased arrays fabricated by use of surface elec...

Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered at 1250 °C for 2h with a heating rate of 10 °C/min. X-ray diffraction analysis of obtained powders and sintered samples was performed in order to investigate changes of the pha...

The growing importance of nonlinear transmission lines for pulsed power and high microwave devices in defense industrial applications motivates material development system optimization. This study investigates composites manufactured with various volume loadings both magnetic (nickel zinc ferrite) dielectric (barium strontium titanate) inclusions a silicone matrix. Increasing the fraction bariu...

We describe a new method of modeling electro-optic (EO) devices, such as lanthanum-modified lead zirconate titanate polarization modulators, that resolves two deficiencies of current methods: (i) the inclusion of depolarization effects resulting from scattering and (ii) saturation of the EO response at strong electric-field strengths. Our approach to modeling depolarization is based on describi...
