This paper presents new technology sensors - helical sensitive elements (HSE) with layered filling. The use of HSE for RF- measurement transducers makes it possible quite efficiently to monitor and measure parameters of various industrial processes and materials. Difficulties arise when monitoring and measuring parameters of liquids such as the conductivity and the continuity of flow, and also the properties of materials with a large relative permittivity (epsilon) or permeability (mu) , such as ferrites. This is caused by the strong screening action of the monitored material or medium having high values of (epsilon) and (mu) on electromagnetic field of the slowed wave in the HSE. As the conductivity increases, the screening becomes even stronger, and this leads to a reduction in the sensitivity and measurement accuracy. The solution of such problems requires the creation and modeling of more complex designs of sensitive elements in which the screening action is weakened. Such an effect can be achieved by matching the field of a hybrid slowed wave to the medium being monitored, utilizing HSE base don layered magnetic and dielectric structures with a smooth variation of the electrodynamic parameters.
