Abstract
In this paper, we present the results of the temperature effect on two-dimensional phononic crystals. Band gap variations of both of the bulk modes and surface modes due to the changing of temperature of the band structure in air/quartz band structure from zero to fifty degrees centigrade are calculated and discussed. The results show that the elastic band gaps can be enlarged or reduced by adjusting the temperature of the band structure. The temperature effect can potentially be utilized for fine-tuning of the phononic band gap frequency and the precise design of filters.
