“…Upadhyay et al [10] conducted a study for sensitivity estimation of metamaterial loaded planar waveguide sensors. Biosensors, material investigation sensors, strain sensors, environmental [11][12][13][14] and agricultural product sensors [15][16][17][18] are the most popular type of MTM sensors. One of the fundamental properties of MTM sensors is that they concentrate and use the electrical specifications of materials [19,20].…”

A metamaterial absorber (MA) based sensor is designed and analysed for various important applications including pressure, temperature, density, and humidity sensing. Material parameters, as well as equivalent circuit model have been extracted and explained. After obtaining a perfect absorption (PA) at around 6.46 GHz and 7.68 GHz, surface current distributions at resonance points have been explained. Since bandwidth and applicability to different sensor applications are important for metamaterial sensor applications, we have realized distinctive sensor demonstrations for pressure, temperature, moisture content and density and the obtained results have been compared with the current literature. The proposed structure uses the changes on the overall system resonance frequency which is caused by the sensor layer's dielectric constant that varies depending on the electromagnetic behaviour of the sample placed in. This model can be adapted to be used in sensor applications including industrial, medical and agricultural products.

“…An open-ended coaxial sensor was developed and used [69] by Abbas et al [69] to determine the oil and water content of olive trees as well as their ripeness. Other authors [70] determined the activation energy of fatty acids obtained from olives in the microwave region. Many authors have also dealt with milk properties [71,72].…”

The growth of diet-related diseases (obesity, diabetes, osteoporosis, and cardiovascular diseases) is becoming an important societal concern and a challenge for a more sustainable society. This has developed important trends in food consumption, including the increasing demand for innovative food with natural attributes and with health claims (foods with added value, enriched foods, and functional foods). The physical properties of food are essential for scientists and engineers at solving the problems in food preservation, processing, storage, marketing, consumption, and even after consumption. In this chapter, we introduce the utilization of physical properties in enriched foods evaluation. The correlations were found between physical properties and other characteristics of foods.
