Wireless communication technology assisted to a huge development during the last two decades, responding to the growing demand for small size and low weight devices such as cell phones and global positioning systems. The need for miniaturization and higher autonomy resulted in the development of new dielectric oxide ceramics with very specific properties, to be applied as dielectric resonators in...
In this work, we report the dielectric properties and microstructure of the Mn doped CaCu3Ti4O12 fibres, grown by the laser floating zone technique, using different pulling rates (Rp). The samples were studied by X-ray diffraction, scanning electronic microscopy, energy dispersive X-ray spectroscopy and AC impedance spectroscopy. The microstructure of CaCu3Ti4−xMnxO12 fibres has been analyzed and...
