An interlaboratory comparison of RF power measurements using automatic power measurement software was carried out among partners of the European Partnership on Metrology project titled “Development of RF and microwave metrology capability II” (RFMicrowave2). The absolute RF power output of a travelling signal generato…

The paper depicts a symmetric microstrip coupler designed for WiMax applications in the frequency range of 2.32 - 2.52GHz. The proposed coupler is comprised of four resonator structures attached in parallel to the ports providing lowered isolation and increased insertion loss and coupling factor. Furthermore, the pres…

Microwave drying has many benefits, namely energy efficiency and process speed when drying high moisture foods such as vegetables, but process optimization is contingent on knowing the properties of material in dynamic environments. Here, we examined microwave drying kinetics of raw cucumber slices (Cucumis sativus L.…

Precise control of drying parameters is essential for energy conservation and product quality in industrial agriculture. Addressing the limitations of traditional real-time monitoring, this research developed a novel measurement system based on the Cavity Perturbation Technique (CPT) to simultaneously analyse the dryi…

Introduction:Early identification of tumor-like changes in bone remains a major diagnostic challenge because conventional imaging methods mainly rely on structural contrast and may involve ionizing radiation, high cost, or limited point-of-care accessibility.In line with the growing interest in bioelectronic and nanoe…

Microplastics are increasingly recognized as a global environmental health threat, yet their detection and characterization remain constrained by the cost, form factor, and throughput of existing analytical tools. Portable micro/nanotechnology-based sensors are emerging to address this need, but most rely on the assum…

In 1958, Haus and Adler [1] introduced the concept of noise measure. Noise measure is a single quantitative metric that provides a comprehensive basis for comparing devices (individual circuits or outcomes of optimization iterations) in terms of their contribution to overall system noise by incorporating both noise fa…

In this article, design, fabrication, and analysis of low profile, easy fabricated microstrip antennas operating in the 0-2.5 GHz frequency range were carried out. These antennas operate at frequencies of approximately 2.3-2.21-2.16 GHz. The antennas consist of three parts such as patch, substrate, and ground plate. S…

Dielectric properties of tree samples belonging to Anatolian chestnut, sessile oak, and Scots pine species were measured in the frequency range of 100 Hz to 1 MHz. Test samples were subjected to three different surface conditions, namely control (CW), two-week water-soaked (SW), and two-coat varnish application (VW).…
