研究目的
To develop a dielectrometer measurement cell for carrying out fast water-containing product analysis in industrial chemical or biomedical laboratories with enough high differential sensibility (at least the order of 0.1%).
研究成果
The new original waveguide cell structure has much better characteristics for the analysis of high-loss liquids than the previous one, with deeper EM field penetration into the liquid layer and lower reflection levels. Experimental results showed good agreement with numerical simulations, making this structure suitable for various applications including product quality control in pharmaceutical companies, food industry, and wine-making plants, as well as for precise analysis of any liquids in laboratories.
研究不足
The asymmetric structure of the new waveguide cell does not allow for rigorous theoretical calculation of the permittivity of the liquid under test based on Maxwell's equations, as was possible with the previous symmetric cell design.
