Abstract:
A resonator, an elastic wave transmission element and a method for fabricating the transmission element are provided. The elastic wave transmission element has a first side and a second side. The elastic wave transmission element includes a plurality of structures sequentially arranged along a direction from the first side toward the second side. Each of the structures has a different defect which is different to each other. The impedance of the structures decreases gradually along the direction. As such, the elastic wave transmission element has an impedance match function.
