In this work, we study the dielectric properties and structure of the BiYWO<inf>6</inf> dielectric resonator (DR) obtained by microwave assisted fast solid state synthesis. The crystal structure of BiREWO<inf>6</inf> (RE&#x003D;rare earth) can be associated to the Bi<inf>2</inf>WO<inf>6</inf> perovskite structure. It was observed that the crystalline(More)
