Software for Modeling QEPAS
and ROTADE Trace Gas Sensors
On this web page, we provide Matlab code and Matlab-with-COMSOL
scripts we developed to model
quartz-enhanced photoacoustic spectroscopy (QEPAS) sensors
and resonant optothermoacoustic detection (ROTADE) sensors.
This research was performed under the auspices and with the support
of the NSF ERC
MIRTHE (Mid Infra-Red Technologies for Health and the Environment).
