Dielectric Resonator Antennas
Nanoparticles of complex oxide materials are synthesized using different solution based techniques. Sol-gel based materials generally tend to be small but agglomerated. This techniques generally yields extremely high purity single phase materials. Using Hydrothermal technique, generally different morphology of the same material can be produced. However, although doping can be modified the exact amount of doping always remain a undertermined factor. Co-precipitation is a powerful method similar to solgel, which can synthesize pure paze materials but with different morphologies. However, chances of phase segregation is more than solgel process.
