Coupled Multi-Parameter Optimization of a Differential Resonant Photoacoustic Cell with Impedance-Matched Pickup for Trace Acetylene Detection

The performance of a resonant photoacoustic (PA) cell depends on coupled geometric and acoustic parameters acting through the acoustic field, thermoviscous boundary losses, and the microphone load. Building on established analytical, numerical, and equivalent-circuit rules for PA-cell design, this work develops a syste...
