We report on the numerical simulations and experimental validation of a microwave planar
sensor based on two coupled rings operating in the 4–6 GHz range. The fabricated sensor is …

In this article, a meander line with parasitic resonator based on ENG metamaterial is
introduced, with nonlinear regression of sensitivity for sensing applications. The unit cell is …

In this work, a compact dielectric sensor for the detection of adulteration in solid and liquid
samples using planar resonators is presented. Six types of filter prototypes operating at 2.4 …

BACKGROUND Microwave sensor technology is considered to be a non‐destructive and
hygienic means for food evaluation and analysis. The rapid progress in microwave sensor …

In this article, we present the use of a metamaterial-incorporated microwave-based sensor
with a single port network for material characterization. The proposed sensor consists of a …

In this study, a novel microstrip antenna sensor with defected ground structure is
investigated to detect the presence of other substances in liquid food samples. The …

BACKGROUND Food adulteration has long been considered a major problem. It
compromises the quality, safety, and nutritional value of food, posing significant risks to …

This paper discusses experimental approaches on properties characterization of magneto-
dielectric (MD) material using Substrate Integrated Waveguide (SIW) structure. The …

The ability of food products to store and dissipate electromagnetic energy is determined by
the material's dielectric properties. In relation to this phenomenon, a non-destructive …

This paper examines intelligent humidity sensors (transducers) as a component of an
automated process control system that converts a controlled physical quantity into a …
