Trace CH<sub>4</sub> Gas Detection Based on an Integrated Spherical Photoacoustic Cell

Trace CH<sub>4</sub> Gas Detection Based on an Integrated Spherical Photoacoustic Cell

This paper presents an integrated spherical photoacoustic cell (SPAC) for trace methane (CH<sub>4</sub>) gas detection. Theoretical analysis and analogue simulations are carried out to analyze the acoustic field distribution of the SPAC at resonant and non-resonant modes. The finite elem...
