Experimental and numerical investigation of a ceramic dielectric resonator (DRA): CaCu3Ti4O12 (CCTO)

Dielectric properties of Nb-doped CaCu3Ti4O12 electroceramics measured at high frequencies

“…Almeida et al [7] produced a dielectric resonator antenna (DRA) from CCTO using a small cylindrical disc of CCTO placed above ground plane. The resonant frequency measurement has confirmed the potential use of this material for small DRA.…”

Dielectric properties of high permittivity ceramics based on Dy2/3CuTa4O12

“…CaCu 3 Ti 4 O 12 (CCTO), an archetypal compound in this family, in ceramic [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18], crystal [2,19,20] and thin film [21][22][23] form, has been extensively studied for the last decade. Numerous publications on CCTO have concerned dielectric properties [1][2][3][4][5][6][7][8][9][10][11]13,14,[16][17][18][21][22][23], microstructure [5][6][7][8][9][10][11]13,…”

Dielectrics Properties and Temperature Dependence of Electron Spin Resonance of Doped Molybdenum CCTO

“…Recently, ACu 3 Ti 4 O 12 oxides type with high dielectric constant were found and CaCu 3 Ti 4 O 12 (CCTO) [1] presented an exceptional behavior with potential technological applications such as capacitors and microwave devices. Values of dielectric constants of CCTO ranging from 3000 to 300,000 have been reported [2][3][4][5] and show that these dielectric properties are very sensitive to manufacturing process, and vary with time, temperature, the sintering atmosphere and the annealing [6]. Authors also report the influence of different doping CCTO solid phase.…”
