Abstract

Since there has been no effort at all in using a microwave cavity resonator in the detection of hydrogen peroxide in water, we propose a simple detection method of hydrogen peroxide concentration based on the well-known microwave cavity perturbation technique for the TM₀₁₀ mode at of a copper cylindrical cavity at 3.48 GHz. From the measurements, we found that the main parameters for cavity perturbation namely center frequency shifts and bandwidth (or quality factor Q) changes both exhibit strong correlation with the concentration.
