• 論文の詳細を見る

• Interdigital transducers (IDTs) with leaky-SAWs propagating on 36° YX-LiTaO_3, and 41° and 64° YX-LiNbO_3 were theoretically analyzed, providing a new equivalent circuit. This equivalent circuit included attenuation constant due to leakage as well as conductance caused by bulkwave radiation. All circuit parameters were derived by solving integral equations. Fundamental experiments showed fairly good agreement between theoretical and experimental results, which gave very accurate design tools for leaky-SAW devices.
