AB  - This article discusses combination of tetragonal crystals with LiTaO3 (LT) thin 
      plate for complete transverse resonance suppression of surface acoustic wave 
      (SAW) devices without k(2) deterioration by manipulating the slowness shape. 
      Besides, better lateral energy confinement is achieved as well by the use of a 
      double bus-bar structure. First, the mechanism of slowness shape manipulation by 
      combining tetragonal crystals is studied. By comparison, YZ-lithium tetraborate 
      (LBO) shows better performance than 69 degrees Y90 degrees X quartz. Then, numerical simulations 
      are carried out using a periodic 3-D finite method assisted by a hierarchical 
      cascading technique (HCT), and the effectiveness of transverse mode suppression 
      by flattening the slowness shape is revealed. Also, the possibility to realize 
      temperature compensation (TC) is discussed owing to the unique material property 
      of LBO. Moreover, the capability of other tetragonal crystals for slowness 
      manipulation is compared, and LBO is the best choice among these tetragonal 
      crystals.
