Novel Microwave Gas Sensor using Dielectric Resonator With ...

+

The sensor uses a microwave planar dielectric resonator operating with whispering gallerymodes. The dielectric resonator (DR) is covered by SnO2 thin film as sensitive layer. A gas adsorption makes the SnO2 effective dielectric parameters changing namely its permittivity. Such changing modifies the resonance frequency of the resonator.

May 11, 2020· 3. Direct vs. Indirect Setups. Figure 2 schematically shows the detection of a representative trace gas (carbon dioxide—CO 2), the main constituents of air (nitrogen—N 2 and oxygen—O 2), as well as often occurring and strongly varying humidity (water—H 2 O), which may also be the cause for crosssensitivities. It depicts the two types of photoacoustic setups that can be …

Gas traces measurement by photoacoustic spectroscopy using ...

+

Photoacoustic spectroscopy is a wellestablished gas traces optical detection technique, which consists in the generation of an acoustic wave in the investigated gas compound excited by a modulated laser beam, and in the detection of this sound wave with a sensitive microphone. The sensitivity of this technique can be greatly enhanced through the use of acoustic resonators.
