Permittivity and permeability parameters of dielectric composites made of ferrite particles coated in a barium titanate (BaTiO3) layer were analyzed and compared against composites of ferrite powders without a dielectric layer. A hydrothermal synthesis process combined barium hydroxide (Ba(OH)2) and titanium dioxide (TiO2) to form the coating of barium titanate around a ferrite core. These barium...
Emerging dielectric materials have been utilized to reduce the size of antennas and advanced pulsed power systems. Metamaterial composites can replace these traditional dielectrics by providing better electromagnetic properties while also being easy to machine into complex shapes. We are presently investigating these metamaterial composites, which have an impedance that can operate at the impedance...
