Successive absorption and refraction of ultrathin molecular nano-films
Zaštita Materijala, 2014 Based on the formed model of nanofilm crystal structures, changes of optical properties due to the presence of borders for the case of symmetrical ultrathin films are theoretically investigated in this paper.

Effect of modifiers on the barium niobate-calcium ceramics structure
Физико-химические аспекты изучения кластеров, наноструктур и наноматериалов, 2022 In this work, the ceramic samples Са0,3Ba0,7Nb2O6 pure and with modifying additives (5%) SrTiO3, KTaO3 or LiTaO3 were obtained by solid-phase synthesis. All studied compositions of ceramics revealed the presence of large and small grains.

Low permittivity epoxy nanoporous composites filled with hollow nanosilica
IET Nanodielectrics, 2019 An epoxy nanoporous composite (NPC) filled with hollow nanosilica exhibits lower permittivity than unfilled epoxy resin. The hollow nanosilica is a silica nanoparticle containing a nanometric closed pore.

Transmission Studies of Left-handed Materials
, 2001 Left-handed materials are studied numerically using an improved version of the transfer-matrix method. The transmission, reflection, the phase of the reflection and the absorption are calculated and compared with experiments for both single split-ring ...

Microwave Interferometry Based On Open-ended Coaxial Technique for High Sensitivity Liquid Sensing
Advanced Electromagnetics, 2017 This paper describes a modified open-ended coaxial technique for microwave dielectric characterization in liquid media. A calibration model is developed to relate the measured transmission coefficient to the local properties of the sample under test.
