Sol-gel synthesis, structure, and dielectric properties of LaLiTiAlO solid solutions.

LaLiTiAlO were synthesized using the sol-gel Pechini route. Ceramic samples were sintered in the temperature range of 1240-1300 °C in the air atmosphere. It was found that in the concentration range of 0.

Y-type hexagonal ferrite-based band-pass filter with dual magnetic and electric field tunability.

This work is on the design, fabrication and characterization of a hexagonal ferrite band-pass filter that can be tuned either with a magnetic field or an electric field. The filter operation is based on a straight-edge Y-type hexagonal ferrite resonator symmetrically coupled to the input and output microstrip transmission lines. The ZnYfilter demonstrated magnetic field tunability in the 8-12 GHz frequency range by applying an in-plane bias magnetic field H provided by a built-in permanent magnet.
