Abstract
PURPOSE:To make a fine adjustment of center frequency by applying an anodic oxidation treatment to the electrode with corrugated surface of metallic steam filter on the piezoelectric material made PCB surface, thus replacing the surface layer with the electricity-insulating material and changing the equivalent surface wave transmitting speed of the electrode unit.
