“…With the increase of water content, the ε r and ε r of agricultural by-product powder at the same frequency increased monotonically. The dielectric properties of rice husk ash and polyester (RHAP) composites over 12-18 GHz was reported by Lee et al [22]. Lee used the rectangular waveguide transmission line method to measure the dielectric properties of the (RHAP) composites [22] and microwave absorption of rice husk reported in [7].…”

This paper presents a review on characterization of agricultural product using various type of microwave sensor. Interaction between EM waves with materials are described. Interaction between microwave and agricultural product are considering a wide range of frequencies and applications such as detection of dielectric properties, moisture content, heating mechanisms, and product control. Each of the Agricultural product has their unique dielectric properties, it can be characterized by frequency dependent parameters such as dielectric properties and moisture content. By analyzing the unique dielectric properties of the agricultural products, the moisture content and the heating mechanisms can be distinguished by measuring the changes in dielectric properties and concentration of agricultural products. Additionally, this paper also emphasis on a clear demarcation of open-ended coaxial probe, planar antenna, rectangular waveguide, and horn antennas as microwave sensor and their applications.

The stabilization of inorganic waste of various nature and origin, in glasses, has been a key strategy for environmental protection for the last decades. When properly formulated, glasses may retain many inorganic contaminants permanently, but it must be acknowledged that some criticism remains, mainly concerning costs and energy use. As a consequence, the sustainability of vitrification largely relies on the conversion of waste glasses into new, usable and marketable glass‐based materials, in the form of monolithic and cellular glass‐ceramics. The effective conversion in turn depends on the simultaneous control of both starting materials and manufacturing processes. While silica‐rich waste favours the obtainment of glass, iron‐rich wastes affect the functionalities, influencing the porosity in cellular glass‐based materials as well as catalytic, magnetic, optical and electrical properties. Engineered formulations may lead to important reductions of processing times and temperatures, in the transformation of waste‐derived glasses into glass‐ceramics, or even bring interesting shortcuts. Direct sintering of wastes, combined with recycled glasses, as an example, has been proven as a valid low‐cost alternative for glass‐ceramic manufacturing, for wastes with limited hazardousness. The present paper is aimed at providing an up‐to‐date overview of the correlation between formulations, manufacturing technologies and properties of most recent waste‐derived, glass‐based materials. © 2016 The Authors.
