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

In this paper, we proposed a polarization-independent terahertz surface plasmon resonance
(SPR) biosensor based on an angular cyclic element structure. The biosensor has the …

In this paper, a complementary split-ring resonator (CSRR)-based patch antenna is
proposed as a microwave sensor to measure the salt concentration of NaCl solution. 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 …

In this paper, a microstrip sensor structure was designed and implemented to detect blood
glucose levels (BGL) based on changes in resonant frequencies, achieved by creating …

This article presents a new planar microwave sensor for displacement measurements. The
sensor is based on a modified triangular-shaped quarter-wavelength resonator that has the …

In this research paper, a novel reconfigurable ring antenna sensor is presented to detect
adulteration in liquids. The suggested antenna sensor is designed to detect and predict salt …

A design of high sensitivity Vivaldi antenna is introduced for detecting the low sugar and salt
concentrations in water. The reason for selecting the Vivaldi antenna configuration is to …

This article communicates an offset-fed split ring loaded slotted-antenna design, testing, and
analysis for different water quality sensor. The antenna was designed to resonate at 10GHz …

In this paper, an antenna sensor based on an electromagnetic bandgap (EBG) structure is
proposed to measure the complex permittivity of liquid under test (LUT). The sensor consists …
