A parameter study of multilayered sensor structures is presented. These consist of planar microwa¨e resonators coated with a thin, sensiti¨e membrane. The influence of the¨arious layers on the sensor characteristics is studied, and design rules are formulated. Two sensors with a moisture-sensiti¨e coating are realized. The experimental results confirm the simulation. ᮊ
ABSTRACT:The contribution to the induced current in a wire inside a conducting box due to field penetration through a narrow slot in comparison with the contribution from leakage through a large aperture has been studied. Different placements of the wire ha¨e been e¨aluated in order to find under which circumstances the narrow slot can be neglected in comparison with the large aperture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
