متن کاملS-band Frequency Spectra
This paper presents a novel design of a microstrip patch antenna with compact nature and the study of various antenna parameters to suit the applications such as WiMax operating in the frequency range of 3.3 – 3.5 GHz and in other applications like fixed satellite services, maritime mobile services etc. covering 2 4 GHz of S-band frequency spectra. It is experimental observed that by placing st...

متن کاملBorn effective charges of barium titanate: Band-by-band decomposition and sensitivity to structural features.
The Born effective charge tensors of Barium Titanate have been calculated for each of its 4 phases. Large effective charges of Ti and O, also predicted by shell model calculations and made plausible by a simplified model, reflect the partial covalent character of the chemical bond. A band by band decomposition confirms that orbital hybridization is not restricted to Ti and O atoms but also invo...
متن کاملSynthesis of phase pure praseodymium barium copper iron oxide.
The control of crystallization of praseodymium barium copper iron oxide, an intermediate temperature solid oxide fuel cell cathode material, has been demonstrated for the first time using a biotemplated sol-gel synthesis technique. The results obtained showed significant improvement in purity, synthesis time, surface area and simplicity over that previously reported.
