Abstract Microwave absorption properties were systematically studied for double-layer carbon black/epoxy resin (CB) and Ni 0.6 Zn 0.4 Fe 2 O 4 /epoxy (F) nanocomposites in the frequency range of 8 to 18 GHz. The nanoparticles synthesized via high energy ball milling with subsequent sintering while black was commercially purchased. materials later incorporated into epoxy fabricate composite structures total thicknesses 3 mm. CB1/F1, which as matching ferrite absorbing layer each thickness 1...
An effective method for extraction of electromagnetic properties bianisotropic biaxial omega-type metamaterial (MM) slabs from waveguide measurements is presented. The relies on S-parameters two MM slab configurations (transverse and longitudinal) to extract endowed with strong coupling. uncertainty analysis performed examining the effect geometrical parameters longitudinal configuration its resonance characteristic. For verification proposed method, constitutive a polyethylene sample are...
Metamaterials (MMs) are artificial materials that have received attention recently because their built-in features create collective electromagnetic effects otherwise impossible, such as negative refraction, and of exotic applications, namely, perfect lens invisibility cloaks. Depending on wave propagation characteristics, MMs possessing normally weak magneto-electric coupling coefficients start to exhibit stronger bianisotropic effects. Therefore, accurate characterization these is...
A new deembedding technique is proposed for relative complex permittivity <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\varepsilon _{r}$ </tex-math></inline-formula> determination of dielectric materials using gated free-space measurements. Its three main features are 1) it does not require any formal calibration procedure (calibration-free); 2) position-insensitive; and 3) extracts ripple-free due to...
We propose an effective microwave method for reference-plane-invariant and thickness-independent constitutive parameters measurement of thin materials.

In addition extraction sample thickness, can also be applied unique retrieval whose electromagnetic properties are yet unknown. have performed uncertainty analysis examine how accuracy improved. Finally, we compared proposed with...
High demand of semiconductor gas sensor works at low operating temperature to as 100 °C has led the fabrication based on TiO2 nanoparticles.

Hybrid parabolic trough concentrators were considered as the basis of co-generation systems, which mainly based on Simultaneous production thermal and electrical energy. In this paper, a model two cogeneration systems consisting collector, combined with cylindrical thermoelectric generator was presented. The collector present configurations forms an annular channel between inner side absorber tube upper surface tubular generator. A heat transfer fluid (Therminol VP1 or hot water) is passed...
The combination of sensing invisible ultraviolet photons and infrared radiation can significantly enhance target recognition by offsetting their own limit in a short range poor spatial resolution. However, the difference wavelength sets unique requirements for materials devices, which makes it hard to establish implementation single detector. In this work, we present design detector with CH3NH3PbCl3 (MAPbCl3) distinguishing IR signals switching its operating mode photo-/thermo-electric...
Measurements of Kβ/Kα intensity ratios in elements with 22⩽Z⩽69 have been carried out by stimulating the emission K characteristic radiation 59.5 keV monochromatic photons. The x-rays were measured using a Si(Li) detector (160 eV FWHM at 5.9 keV). experimental results compared other theoretical and values.
A very promising amplitude-only microwave method is proposed to noniteratively determine the complex permittivity of lossy materials, which possess at least 10 dB attenuation. It utilizes reflection-only measurements, in some instances increases performance determination since accuracy transmission measurements significantly decreases for high-loss materials. The feasible industrial-based applications implementation requires simple components or inexpensive instruments. However, different...
