Abstract
A theoretical method for predicting the resonant frequencies of acoustic resonators with side branches is introduced. This method is successfully extended to microelectromechanical-scale photoacoustic cell resonators with complex side branch structures. Resonant frequencies are calculated to within a few percent of experimental results. The effect of the side branch hole diameter on the resonant frequency is also demonstrated.
