Abstract :
We calculated an improved bimesa structure, ones that has two mesa steps and is suitable for mounting using a two-dimensional finite element method in the X-Y´ region. The frequency differences between clamp and free X-edge conditions were estimated as an index of mounting influences. When the outer mesa height was lower than 20% of the thick area, the frequency differences were less than 10% of standard-type bimesa resonator values. These results indicate that our bi-mesa structure has good separation from the mounting influences
