Sensor array responses to simulant DMMP and EA
2-port SAW resonators operating at 392 MHz.
The interdigital transducers were shaped
with a Gaussian apotization, with a wavelength
of 8 and fingers overlap of 450µm, while the cavity
length was 1276 µm.
Frequency response against time of PEI, PIB and PECH
polymers to different concentrations of DMMP.
The frequency shift normalized to the central frequency
(about 392 MHZ).
